Monoid actions, their categorification and applications
(Bilkent University, 2017-01)
We study actions of monoids and monoidal categories, and their relations with (co)homology theories. We start by discussing actions of monoids via bi-actions. We show that there is a well-defined functorial reverse action ...
Canonical induction, Green functors, lefschetz invariant of monomial G-posets
(Bilkent University, 2019-06)
Green functors are a kind of group functor, rather like Mackey functors, but with a further multiplicative structure. They are defined on a category whose objects are finite groups and whose morphisms are generated by ...
