Title: An invitation to combinatorial Hopf algebras


Abstract: I will tell you what the incidence coalgebra of a category is, 
and when a monoidal product on the category turns it into a bialgebra. 
Trees, skew shapes and bigraphs yield examples. The main result 
describes the overlap with the theory of Hopf quivers which is 
surprisingly (for me) singular. Based on joint work with Lucia Rotheray.
