DESCRIPTION:Just as abelian categories are an abstract setting for modules
  over a ring\, semi-abelian categories are designed to be an abstract sett
 ing for groups and similar algebraic structures.  I will give an introduct
 ion to semi-abelian categories and show how to define commutativity and se
 mi-direct products in them in a way familiar from groups.
