We introduce the notion of an oplax Hopf monoid in any braided monoidal bicategory,
generalizing that of a Hopf monoid in a braided monoidal category in an appropriate way …

In this paper we study Morita contexts between rings without identity. We prove that if two
associative rings are connected by a Morita context with surjective mappings, then these …

The concept of Morita contexts between unital rings or monoids can be generalized using
the concept of wide right Morita contexts [1] in bicategories. For Morita contexts between …

The main aim of the dissertation is to present a way for defining bicategories, double
categories, lax and colax functors between them, where the coherence pentagon and the lax …
