[An intrinsic construction of the core of Casson's invariant]
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.
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.
Mot clés : invariant de Casson, groupe de Torelli, mapping class group
Keywords: Casson invariant, Torelli group, mapping class group
