Distributive Laws and Unramified Graph Coverings
Atabey Kaygun
İTÜ, Turkey
Özet : Distributive laws, also known as ''factorization systems,'' are useful tools. I will start by few examples, and then explain how an unramified graph covering is equivalent to a pair of groupoids linked together with a distributive law. I will also talk about the beautiful Galois theory behind such coverings. Time permitting, I will comment on the homological ramifications of having such pairs.
