Title: An encounter with Erlang, Gauss, Poisson and Ramanujan Abstract: Erlang's formulae describe the probability of blocking, delay or abandonment in three basic qeueing models. Despite (or thanks to) their simplicity, these formulae are among the most celebrated results in Applied Probability. For large systems (for example, call centers with many agents), these formulae become less insightful, and a large body of research is devoted to developing asymptotic approximations of blocking probabilities. This talk is devoted to assessing the quality of such approximations. In passing, we provide new Gaussian approximations of Poisson distributions.

In this talk I will address the link between solvable models of statistical mechanics and algebraic dynamical systems. The main reason to believe in the existence of a strong link is the remarkable coincidence of entropies of many celebrated solvable lattice models (dimer matchings, domino tilings, spanning trees, etc) and entropies of certain algebraic dynamical systems. Even though the question about the existence of such a link was raised almost two decades ago, this problem remained largely inaccessible. The development of the theory of symbolic covers of algebraic dynamical systems has only recently provided a suitable framework. I will describe in greater detail the link between the solvable sandpile models and their algebraic counterparts. The talk is based on a series of joint papers with D. Lind (Seattle) and K. Schmidt (Vienna).

Speaker: Jose BlanchetTitle: Modeling and Efficient Rare Event Simulation of Systemic Risk in InsuranceReinsurance Networks (joint work with Yixi Shi)Date and time: Wednesday 11 April 2012, 11.1512.15Location: Room C1.112, Science Park 904, Amsterdam
We propose a dynamic insurance network model that allows to deal with reinsurance counterparty default risks with a particular aim of capturing cascading effects at the time of defaults. We capture these effects by finding an equilibrium allocation of settlements which can be found as the unique optimal solution of a linear programming problem. This equilibrium allocation recognizes 1) the correlation among the risk factors, which are assumed to be heavytailed, 2) the contractual obligations, which are assumed to follow popular contracts in the insurance industry (such as stoploss and retrocesion), and 3) the interconnections of the insurancereinsurance network. We are able to obtain an asymptotic description of the most likely ways in which the default of a specific group of insurers can occur, by means of solving a multidimensional Knapsack integer programming problem. Finally, we propose a class of provably strongly efficient estimators for computing the expected loss of the network conditioning the failure of a specific set of companies. Strong efficiency means that the complexity of computing large deviations probability or conditional expectation remains bounded as the event of interest becomes more and more rare.

Speaker: Hans MaassenTitle: Quantum information, probability, and statisticsDate and time: Wednesday April 25 2012, 11.1512.15Location: Room C1.112, Science Park 904, Amsterdam
Abstract: Noncommutative or "quantum" probability theory considers random phenomena from the point of view of operator algebras. In this way techniques from probability and statistics can, by generalization beyond commutative algebras, be applied to quantum mechanical systems. In order to illustrate the method, we discuss several topics: limits to the copying of information in connection to the Heisenberg principle, entanglement of quantum systems, in particular under symmetry, and the use of Young diagrams as statistical estimators.

A film by Agnes Handwerk and Harrie Willems. This biographical documentary follows Yuri Ivanovich Manin's stellar career in the "golden years" of Moscow mathematics during the 1960s and 1970s. He was one of the key players in the development of algebraic geometry, at a time when a constellation of brilliant minds  of which Manin's was but one  were conducting outstanding mathematical research. This happened under the structures of a closed society that put severe restrictions on academics (despite diplomatic détente) right up to the fall of the Iron Curtain in 1989. Yuri Manin's brilliance, and his unswerving integrity, helped him to evade the pitfalls of Sovietera academia. His full cooperation with the documentary allows the world a fascinating glimpse into an era of scientific enquiry that is as celebrated as it is underreported. It is about the exceptional life of a mathematician in unusual times, whose passion for his subject, as well as his breadth of thinking, allowed him to forge his own freedom. Internationally recognized for his contribution to mathematics, Manin's many prizes include the Lenin Prize in 1967, the Brouwer Gold Medal in 1984 and the Georg Cantor Medal in 2002. The length of the documentary is 57 minutes.

Speaker: Hans ZwartTitle: Linear port Hamiltonian SystemsDate and time: Wednesday 23 May 2012, 11.1512.15Location: Room G4.15, Science Park 904, Amsterdam
The field of infinitedimensional systems theory has become a wellestablished field within mathematics and systems theory. There are basically two approaches to infinitedimensional linear systems theory: an abstract functional analytical approach and a PDE approach. Many physical systems can be formulated using a Hamiltonian framework. This class contains ordinary as well as partial differential equations. Each system in this class has a Hamiltonian, generally given by the energy function. In the study of Hamiltonian systems it is usually assumed that the system does not interact with its environment. However, for the purpose of control and for the interconnection of two or more Hamiltonian systems it is essential to take this interaction with the environment into account. This led to the class of portHamiltonian systems. For portHamiltonian systems described by ordinary differential equations this approach is very successful. PortHamiltonian systems described by partial differential equation is a subject of current research.
In this presentation, we combine the abstract functional analytical approach with the more physical approach based on Hamiltonians. For a class of linear infinitedimensional portHamiltonian systems we derive easy verifiable conditions for wellposedness.

Speaker: Gregory TemnovTitle: On a class of distributions stable under random summationDate and time: Thursday 31 May 2012, 14:00Location: D1.113
We study a family of distributions having a property of stabilityunderaddition, provided that the number (say, r) of random variables in a sum is also a random variable. We call the corresponding property rstability and investigate the situation when the semigroup generated by the generating function of r is commutative. A new case in this class of distributions arises when generating functions are linked with Chebyshev polynomials. The random summation analogy of the normal distribution corresponds to the hyperbolic secant distribution. We analyse the link with classical stable distributions, as well as with some other families, and discuss the outlook for applications. Joint work with Lev B. Klebanov, Charles University Prague

Speaker: Professor Motohico Mulase (UC Davis, California)Title: Higher genera Catalan numbers and EynardOrantin theoryDate and time: Monday 9 July 2012, 16.00 hrsLocation: B0.209Abstract: The Catalan numbers have many different interpretations. Accordingly, they have also many generalizations. In this talk I will present a straightforward highergenus extension of the Catalan numbers for every genus g, so that the original Catalan numbers are the simplest case of g = 0. Using the pairofpants decomposition of a surface, we can derive an elegant recursion formula for these generalized Catalan numbers. Again the g = 0 restriction recovers the original Catalan recursion. Now let's compute the Laplace transform of these highergenus Catalan numbers. Surprisingly they satisfy a system of equations, such as an integrable system of PDEs of the KdVtype, and a system of integral transform equations.
I will explain how this simple theory provides a nontrivial mathematical example of the conjectural theory being built by many physicists, including GukovSulkowski, Marino, EynardOrantin, and others. This theory has, and still is expected to continue, to give us an amazing geometric insight of quantum invariants such as colored Jones polynomials and (open) GromovWitten invariants.

Automorphic forms of various types have arisen repeatedly in diverse areas of physics. In this talk, I shall discuss two related instances of this type, which involve a recentlydefined class of functions called mock theta functions. The first instance is connected to quantum black holes in string theory, and the second is connected to the representations of the largest Mathieu group M24. I will explain these connections and discuss some properties of these functions.

Speaker: Koen De TurckTitle: Poisson's equation for Markov chains and its use in perturbationsDate and time: Wednesday 3 October 2012, 11.1512.15Location: Room C1:112, Science Park 904, Amsterdam
I will talk about two recent research topics of mine in which Poisson's equation plays a crucial role. I will start out by introducing Poisson's equation in a Markov chain context, and point out how it relates to the (to some) more familiar notion of Poisson's equation in PDE theory. Determining solutions for Poisson's equation for Markov chains, as in physics, often proceeds via Green's functions. In the first part of the talk, I will derive explicit expressions for the transforms of these Green's functions. It appears this can be done for a surprisingly large class of Markov chains. The second part of the talk centres around perturbation of Markov chains. I will illustrate, by means of a concrete example, a powerful but often hard to formalise samplepath technique and contrast it with the direct but often rather longwinded approach. I conclude the talk by showing how a formulation in terms of Poisson's equation provides the best of both worlds.

The first lecture is on Friday 5 October, 16.0017.00 hour, Science Park 904, room A1.08 and the second lecture on Tuesday 9 October, 16.0017.00 hour, Science Park 904, room B0.209.Short abstract:
We explain spectral types and fractional transformations of Fuchsian differential equations. The corresponding transformations of fundamental properties of their solutions such as their reducibility and connection coefficients are explicitly given and we calculate them for the rigid equations in terms of a KacMoody root system. This analysis is also applicable to the equations with irregular singularities.See a longer abstract on http://www.science.uva.nl/math/NewsandEvents/newsitem.php?id=1349264146.

Dynamical systems with a network structure arise in applications that range from statistical mechanics and electrical circuits to neural networks, systems biology, power grids and the world wide web. In this talk I will explain what it means for a coupled cell network to possess the "semigroup(oid) property". Networks with this property form a Lie algebra and we recently developed a method to compute their local normal forms near a dynamical equilibrium. This helped us understand and predict certain seemingly anomalous bifurcations in network systems.

Prof. dr. J.H. (Harry) van Zanten, currently professor of Statistics at Eindhoven University of Technology, has been appointed as professor of Mathematical Statistics at the Faculty of Science of the University of Amsterdam. He will take office at KdVI, starting September 2012.
Harry van Zanten is doing research on statistical methods for complex highdimensional systems. Increasingly fields of application use models in which a very large number of unknown parameters has to be estimated by using the available data. Classical statistical methods can often not be used in such situations. Van Zanten's research aims at finding new methods and studying their properties. In particular he is studying nonparametric Bayesian methods.
