Christopher Rasmussen (Wes): A (Necessarily Incomplete) Introduction to Frobenioids

Abstract:  A man who knows a little is sometimes more dangerous than a man who knows nothing at all.

In his approach to proving the ABC Conjecture, Mochizuki relies on the concept of a Frobenioid, which in his own words is ``a sort of a category-theoretic abstraction of the theory of divisors on [models of global fields].''

In the present talk, we will attempt to carefully introduce the notion of a Frobenioid and provide a small amount of context. Nothing will be assumed beyond a basic knowledge of category theory and some standard algebra.
