*Jan Maas (IST Austria): „Optimal transport and the isoperimetric 
inequality”*

**

Abstract:

Suppose that you are given an amount of mass, located at different 
spatial locations ("factories"), which needs to be transported to 
prescribed final destinations ("consumers"). How much mass should be 
transported from each factory to each consumer, in order to minimise the 
total transport costs? In recent years, this innocent looking 
optimisation problem has found many applications in analysis,

geometry and probability. I will give a brief introduction to the topic, 
and show how one can use optimal transport to give an elegant proof of 
the isoperimetric inequality, which goes back to Gromov.

*Jan Maas (IST Austria): „Optimal transport in discrete probability“*

**

Abstract/:/

Optimal transport has become a flourishing mathematical field, yielding 
new connections between analysis, probability and geometry. Among the 
highlights are new interpretations of heat flow and Ricci curvature in 
terms of a geometric structure on the space of probability measures 
induced by the Wasserstein metric of optimal transport. In discrete 
settings this structure degenerates, and the theory

appears to break down. We present a new class of transportation metrics, 
which allow us to apply ideas from optimal transport to problems in 
discrete probability. In particular, we obtain a notion of discrete 
Ricci curvature, with interesting geometric and probabilistic 
consequences. We will also show examples of graphs and interacting 
particle systems for which explicit curvature bounds can be obtained**
