Nous donnons une nouvelle construction cohomologique du cœur de l'invariant de Casson et nous donnons un nouveau calcul de ses valeurs sur les générateurs du sous- groupe de Johnson du mapping class group.
We give a new cohomological construction of the core of Casson's invariant and give a new computation of its values on the generators of the Johnson subgroup of the mapping class group.
Mot clés : invariant de Casson, groupe de Torelli, mapping class group
Keywords: Casson invariant, Torelli group, mapping class group
