Abstract: Two boundary diagram algebras (e.g. graded braid groups, Hecke algebras,
Brauer algebras) arise as tensor power centralizer algebras, algebras of commuting
operators for a Lie group action on a tensor space, and show ties to already familiar
objects. In particular, one two boundary centralizer algebra in type A is isomorphic
to a graded Hecke algebra for a reflection group of type C. In this talk, I will construct
this algebra, discuss its representations and their combinatorial structure, and provide
its relation to type C objects.
