Málstofa í stærðfræði Fyrirlesari: Thomas Selig, University of Strathclyde Titill: EW-tableaux, permutations and recurrent configurations of the sandpile model on Ferrers graphs. Staðsetning: VRII, V-147 Tími: Miðvikudagur 27. júní kl. 10:30 Ágrip: The Abelian sandpile model (ASM) is a dynamic process on a graph. More specifically, it is a Markov chain on the set of
Málstofa í stærðfræði Fyrirlesari: Delphin Sénizergues, Université Paris 13 Titill: Random metric spaces constructed using a gluing procedure Staðsetning: VRII-V147 Tími: Mánudagur 18. júní kl. 10:50 Ágrip: I will introduce a model of random trees which are constructed by iteratively gluing an infinite number of segments of given length onto each other. This model can
Málstofa í stærðfræði Fyrirlesari: Adam Timar, Renyi Institute, Budapest Titill: Allocation rules for the Poisson point process Staðsetning: Árnagarður 101. Tími: Föstudagur 3. júní, klukkan 13:20-14:20. Ágrip: Consider the Poisson point process in Euclidean space. We are interested in functions on this random point set whose value in each configuration point is given by some
Málstofa í stærðfræði Fyrirlesari: Jakob Björnberg Titill: Random permutations and quantum Heisenberg models Staðsetning: V-157, VRII. Tími: Föstudagur 1. apríl kl. 13:20. Ágrip: The interchange process (or random-transposition random walk) is a model for random permutations which is closely related to a model from quantum statistical physics (the ferromagnetic Heisenberg model). In fact, certain ‘cycle-weighted’
Málstofa í stærðfræði Fyrirlesari: François David Titill: Planar maps, circle patterns and 2D gravity Staðsetning: V-157, VRII. Tími: Föstudagur 11. mars kl. 13:20. Ágrip: I present a model of random planar triangulations (planar maps) based on circle patterns and discuss its properties. It exemplifies the relations between discrete random geometries in the plane, conformally invariant
Málstofa í stærðfræði Fyrirlesari: Guenter Last Titill: Second order properties of the Boolean model and the Gilbert graph Staðsetning: V-157, VRII. Tími: Föstudagur 30. október, klukkan 15:00-16:00. Ágrip: The Boolean model is a fundamental model of stochastic geometry and continuum percolation. It is a random subset of Euclidean space that arises as the union of
Málstofa í stærðfræði Fyrirlesari: Páll Melsted Titill: Space Utilization of Cuckoo Hashtables Staðsetning: V-157, VRII. Tími: Föstudagur 23. október, klukkan 15:00-16:00. Ágrip: We study the space requirements for Cuckoo Hashing. This can be reduced to the following question in Random Graphs. We are given two disjoint sets L,R with |L|=n=alpha*m and |R|=m. We construct a
Málstofa í stærðfræði Speaker: Hermann Thorisson, University of Iceland Title: Mass-Stationarity, Shift-Coupling, and Brownian Motion Staðsetning: Naustið, Endurmenntun (hér) Tími: Fimmtudagur 28. maí, klukkan 15:00-16:00. Ágrip: After considering mass-stationarity and shift-coupling briefly in an abstract setting, we focus on the special case of stochastic processes on the line associated with diffuse random measures. The main

Málstofa í stærðfræði Fyrirlesari: Jakob Björnberg, Chalmers Tekniska Högskola, Göteborg Titill: Percolation in random quadrangulations of the half-plane Staðsetning: V-157, VRII Tími: Mánudagur 17. nóvember, frá 15:00 til 16:00. Ágrip: The topic of random planar quadrangulations (and, more generally, random planar maps) is of interest to probabilists, combinatorialists and physicists alike. Recent years have seen
