Professor Paul Ehling (BI Norwegian Business School): Asset Prices and Portfolio Choice with Learning from Experience

Paul Krühner (University of Oslo) holder et seminar med tittelen: On uniqueness of Markov processes described by a symbol.

Bas Jordans (UiO) will give a talk with title: Real dimensional spaces in noncommutative geometry

Abstract:

In noncommutative geometry geometric spaces are given by spectral triples. In this talk we consider a generalisation of these spectral triples to semifinite spectral triples. In analogy to the classical case it is possible to construct the product of two semifinite spectral triples. We will construct this product and derive properties thereof. Also we will describe for each z\in(0,\infty) a semifinite spectral triple which can be considered as having dimension z. As an application these "z-dimensional" semifinite triples will be used for two regularisation methods in physics.
