In particular, the well established context of semiabelian categories= provides a natural setting for studying the interplay between categorical and a= lgebraic aspects of actions, with respect to internal structures that may be d= efined. Nevertheless, more general settings are worth to be considered ( lex= pointed categories with sums, protomodular categories...) Keywords of the meeting are: the representability of actions, suffici= ent conditions for their existence, universal actions, categorical semi-= direct product and constructions, internal groupoids and internal crossed mo= dules, internal commutator theory, cohomological implications. The workshop is intended to reflect its etymology, in order to give t= he participants a fruitful opportunity of debate and exchange experience= s about the subject. That is the reason why after every lecture there will be time for inf= ormal discussions. The backbone of the meeting are the lectures of the invited speakers:= Dominique Bourn (Universit=E9 du Littoral), Marino Gran (Universit=E9 du Littor= al) and Enrico Vitale (Universit=E9 Catholique LLN). Lectures are scheduled on Thur= sday 26th and Friday 27th (morning and afternoon), and on Saturday 28th (only m= orning). Attendance is open to everyone and other contributions on related top= ics will be considered with pleasure. The workshop will take place at the Math Department of Universit=E0 d= egli Studi, Milan, Italy. Detailed program, logistic and further information will follow. ---------------------------------------------------------------------= - Organizing committee: Stefano Kasangian, Sandra Mantovani, Giuseppe M= etere.
