Yoshiaki Inoue (Osaka University) Sample-Path Analysis of the Age of Information (AoI) and Its Applications to FCFS Single-Server Queues The age of information (AoI) is a metric for the freshness of information, which is defined as the time difference between the current time and the time-stamp of the information. Analysis of the AoI has been attracting a considerable attention in recent years, because of its wide applicability to systems where the freshness of information is the primary concern. In this talk, a general formula for the probability distribution…

Lutz Warnke (Georgia Institute of Technology) A dynamic view on the probabilistic method: random graph processes Random graphs are the basic mathematical models for large-scale disordered networks in many different fields (e.g., physics, biology, sociology). Since many real world networks evolve over time, it is natural to study various random graph processes which arise by adding edges (or vertices) step-by-step in some random way. The analysis of such random processes typically brings together tools and techniques from seemingly different areas…

Nicolas Broutin (Sorbonne Université) Fragmentations and tree-like fractals: a functional fixed-point approach I will review some models and recent results where ``fixed-points'' approach or the ``contraction method'' have played a central role. Recursive partitioning schemes are central to many applications, starting with efficient data structures based on the divide-and-conquer paradygm. For more than 25 years now, arguments based on Banach fixed theorem have long been used to prove ``softly'' the convergence in distribution of associated real-valued random variables in the…

### NWO-JSPS joint seminar: Computations on Networks with a Tree-Structure: From Theory to Practice

Sponsored by Summary Dynamic programming based on tree decomposition is one of the most successful approaches for solving important hard problems on networks, with problems ranging from several application areas (including operations research, computational biology, etc.). In theory, Bodlaender's algorithm and Courcelle's theorem give for a large collection of problems algorithms that solve them in time linear in the number of vertices, assuming we have a graph or network with the appropriate structure (i.e., the treewidth…

### "Multidimensional Queues, Risk, and Finance"

Sponsored by Summary The aim of the "Multidimensional Queues, Risk, and Finance" workshop is to bring together researchers from several fields within applied probability theory. The overarching theme is multidimensional stochastic analysis, including topics in queueing networks, limit order books and (re)insurance. A wide range of methods and techniques will be presented: exact, approximate, asymptotic and simulation. Organizers Onno Boxma TU Eindhoven Stella Kapodistria TU Eindhoven David Koops University of Amsterdam Speakers Keynotes Hansjörg Albrecher Université…

Andreas Kyprianou (University of Bath) Some strange results in fragmentation-coalescence models We analyse a class of fragmentation-coalescence processes defined on finite systems of particles organised into clusters. Coalescent events merge multiple clusters simultaneously to form a single larger cluster, while fragmentation breaks up a cluster into a collection of singletons. Under mild conditions on the coalescence rates, we show that the distribution of cluster sizes becomes non-random in the large-scale limit. Moreover, we discover that, in the limit of small…

Joris Mulder (Tilburg University) The Matrix-F Prior for Estimating and Testing Covariance Matrices The matrix-F distribution is presented as prior for covariance matrices as an alternative to the conjugate inverted Wishart distribution. A special case of the univariate F distribution for a variance parameter is equivalent to a half-t distribution for a standard deviation, which is becoming increasingly popular in the Bayesian literature. The matrix-F distribution can be conveniently modeled as a Wishart mixture of Wishart or inverse Wishart distributions,…

### Energy-Open 2018

Sponsored by Summary Global warming, climate agreements, EU policies to reduce CO2 emissions and many national energy programs reflect the need to make our energy systems more sustainable. This process, called energy transition, entails a fundamental change of the energy system from a centralized system with electricity production mainly based on fossil fuels to a decentralized local system based on sustainable energy production based on e.g. solar, wind, tidal, hydro or geothermal sources. Other changes include the ongoing growth of…
