Jan-Erik Solheim, Institutt for teoretisk astrofysikk, UiO

Bora Yalkinoglu will give a talk entitled: Introduction to p-adic Bost-Connes systems.

Abstract: In this talk we want to give a gentle introduction into the recently emerging theory of p-adic Bost-Connes systems. In the first part of the talk, after reviewing the necessary background from p-adic analysis and number theory, we will explain recent work of Connes and Consani on certain p-adic representations of the classical BC-system. In the second part of the talk we will discuss recent work on generalizations of the work of Connes and Consani and, further, point out several open problems for further research.

For simplisielle mengder X og Y gir projeksjonene X x Y -> X og X x Y -> Y fra produktet ned p? henholdsvis f?rste og annen faktor opphav til en simplisiell avbildning f : Sd( X x Y ) -> Sd X x Sd Y fra den normale oppdelingen av produktet til produktet av oppdelingene. Vi viser at for endelige simplisielle mengder X og Y er denne en simpel avbildning, det vil si at n?r vi g?r over til topologiske rom s? er punktinversene |f|^{-1}(p), p element i |Y|, kontraktible.

Gjesteforelesning ved professor Paul A. Wender.

In nature, groups of individuals organize globally using only local information. For instance, in a school of fish, there are no external forces to coordinate the group, no leader to guide them. Several mathematical models have been proposed to describe self-organization. In this talk, we will consider two of the most famous models; the Keller-Segel model for bacterial chemotaxis and the Cucker-Smale model for flocking. The emphasis will be on recent mathematical results and remaining open questions. Starting from the microscopic description on particle level, we will discuss the derivation of mesoscopic and macroscopic models at the continuum level. Since the motivation for deriving continuum models is largely numerical, we will also discuss distinct numerical challenges with the resulting models.
