Inn'formal Probability Seminar

This seminar is organized by Ecaterina Sava-Huss and Alexander Glazman.

The idea is to discuss recent exciting research developments in the field of Probability (in a broad sense). Some talks are given by speakers invited from other universities but this is also a place for everybody in Innsbruck to share with each other their recent results - or just something cool that we have read. The seminar is very informal and there is always a lot of discussions during the talks (so they tend to last a little longer…).

Each talk will start by an introductory part (~30min), where the speakers will explain some basic concept in their research and the motivation behind.

Please write to Sasha (alexander.glazman@uibk.ac.at) if you want to be on the mailing list.

Upcoming talks

Time and place: Tuesdays 15:30-16:30, HS 10 (Architekturgebäude). Sometimes, the probability seminar will be replaced by the monthly mathematical colloquium, which is dedicated to a broader audience. The colloquium takes place Wednesdays at 15:30.
