Ramsey Theory, Sparsity and Limits (Combinatorics and Model Theory)

Colloquium presented by Jaroslav Nešetřil (Charles University, Prague)

Several combinatorial problems are treated in the context of model theory. 
We survey three such instances which were investigated recently, coming 
from  Ramsey theory, sparsity of graphs and limits of sequences of structures.
These are diverse areas but share some properties where the connection to 
model theory is non-trivial and interesting. It also presents several open 
problems of interest to both combinatorics and model theory.
