INTERNAL ACTIONS and INTERNAL STRUCTURES


WORKSHOP in CATEGORICAL ALGEBRA
Milano, 26th - 27th - 28th  october 2006

Purposes

The aim of the workshop is to consider the notion of internal action in different categorical contexts and to relate it with internal structures defined thereby.
In particular, the well established context of semiabelian categories provides a natural setting for studying  the interplay between categorical and algebraic aspects of actions, with respect to internal structures that may be defined. 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, sufficient conditions for their existence,  universal actions, categorical semi-direct product and constructions, internal groupoids and internal crossed modules, internal commutator theory, cohomological implications.

The workshop is intended to reflect its etymology, in order to give the participants a fruitful opportunity of debate and exchange experiences about the subject.
That is the reason why after every lecture there will be time for informal discussions. 

 

Lectures


Lectures are scheduled on Thursday 26th and Friday 27th (morning and afternoon), and on Saturday 28th (only morning).

Abstracts

Attendance is open to everyone and other contributions on related topics will be considered with pleasure.
