SUMMARY:Jaiung Jun (전재웅)\, The Hall algebra of the category of matroids
DESCRIPTION:To an abelian category A satisfying certain finiteness conditions\, one can associate an algebra H_A (the Hall algebra of A) which encodes the structures of the space of extensions between objects in A. For a non-additive setting\, Dyckerhoff and Kapranov introduced the notion of proto-exact categories\, as a non-additive generalization of an exact category\, which is shown to suffice for the construction of an associative Hall algebra. In this talk\, I will discuss the category of matroids in this perspective.
