Fountainfest "Semigroups, categories and automata", University of York, U.K.
In this talk we will present some of the results obtained with J. Fountain.
Special attention will be given to the discussion of the structure of various classes of proper (one sided) abundant semigroups as well as to the existence of proper covers.
