$C_{\infty}$STRUCTURE ON THE COHOMOLOGY OF THE FREE 2NILPOTENT LIE ALGEBRAMichel DuboisViolette, Todor PopovLaboratoire de Physique Theorique, UMR 8627, Universite Paris XI, Batiment 210, F91 405 Orsay Cedex, France; Theoretical Physics Division, Institute for Nuclear Research and Nuclear Energy, Bulgarian Academy of Sciences, Sofia, BulgariaAbstract: We consider the free 2step nilpotent Lie algebra and its cohomology ring. The homotopy transfer induces a homotopy commutative algebra on its cohomology ring which we describe. We show that this cohomology is generated in degree 1 as $C_\infty$algebra only by the induced binary and ternary operations.
