Workshop on Algebra

Lisbon 2010

I am scheduled to give one talk entitled Morita equivalence of semigroups with local units

The abstract for this talk can be found here.
This also contains all the references and more details on the background to the theory.

My lecture can be found here.
These are rather scrappy notes, but in ouline I shall do the following:
briefly sketch out the background, formally define when two semigroups with local units are Morita equivalent,
show that their Morita equivalence is determined by the equivalence of their Cauchy completions, explain how the Rees theorem
and McAlister's theory of locally inverse semigroups can be viewed as contributions to Morita theory, describe the characterization of Morita equivalence in terms of enlargements and, finally, outline some of the important consequences of the Morita theory of inverse semigroups.
