Málstofa í stærðfræði Fyrirlesari: Suresh Nampuri Titill: Mock modular forms and black hole counting Staðsetning: V-156, VRII. Tími: Miðvikudagur 21. október, klukkan 15:00-16:00.
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 Fyrirlesari: Matthias Hamann Titill: Accessible groups and graphs Staðsetning: V-157, VRII. Tími: Föstudagur 2. október, klukkan 15:00-16:00. Ágrip: The talk falls into two parts. First, we give an overview of the group theoretical concept of accessibility and the main results in this area. In the second part, we define the graph theoretical
Málstofa í stærðfræði Fyrirlesari: Arkadiusz Lewandowski Titill: Some remarks on holomorphically contractible systems. Staðsetning: V-157, VRII. Tími: Föstudagur 25. september, klukkan 15:00-16:00. Ágrip: We shall discuss the ideas behind the holomorphically contractible systems. As examples, we introduce systems of Carathéodory and Kobayashi pseudodistances. We shall discuss some properties of those objects with particular accent put
Málstofa í stærðfræði Fyrirlesari: Georg Schumacher Titill: Hyperbolicity of moduli spaces. Staðsetning: V-157, VRII. Tími: Föstudagur 18. september, klukkan 15:00-16:00. Ágrip: We give an overview about the concept of hyperbolicity of complex manifolds. We compare the notion of the Liouville property (Brody hyperbolicity), hyperbolicity in the sense of Kobayashi, and the concept of negative curvature.
Málstofa í stærðfræði Fyrirlesari: Florian Lehner Titill: Cops, robbers, and infinite graphs Staðsetning: V-157, VRII. Tími: Föstudagur 11. september, klukkan 15:00-16:00. Ágrip: Pursuit-evasion based searching, also known as the game of cops and robbers is a game on a graph between two players, $C$ (the cop) and $R$ (the robber). The rules are as follows:

Ágrip: Studying the (long-term) behavior of the Kähler-Ricci flow on mildly singular varieties, one is naturally lead to study weak solutions of degenerate parabolic complex Monge-Ampère equations. The purpose of this lecture
Málstofa í stærðfræði Fyrirlesari: David Tong Titill: The Supersymmetric Quantum Hall Effect Staðsetning: Naustið, Endurmenntun. Tími: Þriðjudagur 25. ágúst, klukkan 15:00-16:00. Ágrip: I’ll describe the solution to a supersymmetric, but non-relativistic, gauge theory in d=2+1 dimensions. The ground states are given by the Laughlin wavefunctions describing the fractional quantum Hall effect. The model reveals explicit
