Málstofa í stærðfræði Fyrirlesari: Hermann Þórisson Titill: On the Skorohod Representation Staðsetning: Naustið, Tæknigarði Tími: Þriðjudaginn 11. október kl. 12:30-14:00 Ágrip: According to the Skorohod representation theorem, convergence in distribution to a limit in a separable set is equivalent to the existence of a coupling with elements converging a.s. in the metric. A density analogue […]

Málstofa í stærðfræði Fyrirlesari: Séverine Biard, University of Iceland Titill: On pseudoconvex domains and some of their applications Staðsetning: V-158, VRII Tími: Mánudaginn 10. október kl. 15:00 Ágrip: One of the most commonly studied object in several complex variables is pseudoconvex domains, which I will introduce. Domains of holomorphy in , they are studied in
Málstofa í stærðfræði Fyrirlesari: Erik Broman, Chalmers University of Technology and Gothenburg University Titill: Infinite range continuum percolation models Staðsetning: V-158, VRII Tími: Mánudaginn 3. október kl. 15:00 Ágrip: In the classical Boolean percolation model, one distributes balls in in a random, homogeneous way. The density of these balls is controlled by a parameter Depending
Málstofa í stærðfræði Fyrirlesari: Rögnvaldur Möller, University of Iceland Titill: Highly-arc-transitie digraphs of prime out-valency Staðsetning: V-158, VRII Tími: Mánudaginn 19. september kl. 15:00 Ágrip: Joint work with Primoz Potocnik, Ljubljana, and Norbert Seifter, Leoben. The concept of a highly-arc-transitive digraph was defined by Cameron, Praeger and Wormald in a paper that appeared in 1993.
Málstofa í stærðfræði Fyrirlesari: Daniel Friedan, Rutgers University and University of Iceland Titill: Quasi Riemann Surfaces Staðsetning: TG-227 (Tæknigarður, 2. hæð) Tími: Föstudagur 26. ágúst kl. 13:20. Ágrip: This will be a talk about some speculative mathematics (analysis) with possible applications in quantum field theory. I will leave any mention of quantum field theory to
Málstofa í stærðfræði Fyrirlesari: Brittany A. Erickson Titill: A Finite Difference Method for Plastic Response with an Application to the Earthquake Cycle Staðsetning: V-157, VR-II. Tími: Mánudagur 8. ágúst kl. 13:20. Ágrip: We are developing an efficient, computational framework for simulating multiple earthquake cycles with off-fault plastic response. Both rate-independent and viscoplasticity are considered, where
Málstofa í stærðfræði Fyrirlesari: Anthony Bonato Titill: Conjectures on Cops and Robbers Games on Graphs Staðsetning: TG-227 (Tæknigarður, 2. hæð) Tími: Fimmtudagur 30. júní kl. 13:20. Ágrip: The game of Cops and Robbers gives rise to a rich set of conjectures, mainly associated with the cop number of a graph. Arguably the most important such
Málstofa í stærðfræði Fyrirlesari: Sylvain Arguillère Titill: Constrained Shape Analysis Through Flows of Diffeomorphisms Staðsetning: TG-227 (Tæknigarður, 2. hæð) Tími: Föstudagur 24. júní kl. 13:20. Ágrip: The general purpose of shape analysis is to compare different shapes in a way that takes into account their geometric properties, such as smoothness, number of self-intersection points, convexity…
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

Staðsetning: TG-227, (tæknistofan, annarri hæð í Tæknigarði) Tími: Föstudagur 20. maí kl. 13:20. Ágrip: 2d non-linear sigma models are widely used in high and low energy physics. In my talk I will present how to compute the one-loop anomalous dimension for
