Adjunction in the absence of identity

Abstract: In this talk I plan to present and discuss a rather weak bicategorical setup in which one can talk about genuine adjunctions. I will roughly describe the main motivation coming from representation theory of finitary 2-categories (or bicategories) and make some parallells with the structure theory of finite semigroups. I will try to explain how this approach simplifies some results but also makes some other results much more difficult. This is a joint work with Hankyung Ko and Xiaoting Zhang.
