Dear all, 

This week we will have two presentations by two of our new postdocs: 

1. Anna Limbach: From Graphs to Graphons and Back

This talk gives an introduction to graphons from two perspectives --
once, as the limit objects of sequences of dense graphs and once as a
source to generate homogeneous random graphs.
We take a look at recent findings and current open problems.

2. Niloufar Fuladi: Discrete Surfaces, Decompositions, and Crossing Numbers

In this talk, I will introduce graphs embedded on surfaces and discuss their
combinatorial and geometric representations. Such embeddings provide discrete
models of continuous surfaces, enabling a range of computational and structural
questions. In particular, I will focus on problems involving short
decompositions of surfaces and low-complexity drawings, including the
computation of short canonical decompositions and bounds on crossing numbers.

We meet at 9:50 in S11.
