WORKSHOP in CATEGORICAL ALGEBRA Milano, 26th - 27th - 28th october 2006 |
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.
- Dominique Bourn (Université du Littoral) - Split extension classifier, actions representation and associated classification properties
- Marino Gran (Université du Littoral) - Internal groupoids and crossed modules
- Enrico Vitale (Université Catholique LLN) - Schreier theory and obstruction theory via categorical groups
Lectures are scheduled on Thursday 26th and Friday 27th
(morning and afternoon), and on Saturday 28th (only morning).
Attendance is open to everyone and other contributions on related topics
will be considered with pleasure.
The workshop will take place at the Math Department of Università degli Studi di Milano, Italy. (Here is a city map to aid your orientation in Milan)
To get information how to reach the Department, located in Via Saldini
50, Milano, please go to our
direction's page
Maybe, the best thing you can do is to look for your best choice on
