Representations and Cohomology of n-ary multiplicative Hom-Nambu-Lie algebras (1010.5896v2)
Published 28 Oct 2010 in math.RA and math.RT
Abstract: The aim of this paper is to provide cohomologies of $n$-ary Hom-Nambu-Lie algebras governing central extensions and one parameter formal deformations. We generalize to $n$-ary algebras the notions of derivations and representation introduced by Sheng for Hom-Lie algebras. Also we show that a cohomology of $n$-ary Hom-Nambu-Lie algebras could be derived from the cohomology of Hom-Leibniz algebras.
