The fundamental mechanisms of plasticity in inorganic glasses are distinctly different from those in crystalline metals. Whereas dislocations and their mobility require plasticity in metals, mechanisms responsible for permanent deformation in glasses are to be looked at the atomistic scale. The lecture will deal with this and will involve topics such as for instance constitutive material laws, plasticity theory, dislocation theory, computational mechanics, multiscale analysis, finite element methods, crack modelling, etc.

Vincent Keryvin is professor at  Department of Materials Engineering (LIMATB), University of South-Brittany, Lorient, France.

Simen Rustad (UiO) will give a talk with title  "Construction of Bost-Connes type systems for function fields".

Abstract: I will try to indicate how Benoit Jacob's construction of a Bost-Connes  type system for function fields fits into a more general framework.

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 på henholdsvis første 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 når vi går over til topologiske rom så er punktinversene |f|^{-1}(p), p element i |Y|, kontraktible.
