A-infinity structures on coalgebras

Prof. N. Iwase (Kyushu University)

Monday 7th January, 2013 15:00-16:00 203 (nb: room change)


We shall introduce versions of an internal A-infinity category with and without unit. It is meant to construct an algebraic counterpart of two-sided bar construction which should give a new algebraic invariant for Lusternik-Schnirelmann category.
