Notes on Formal Deformations of Homassociative and HomLie Algebras
(2007) In Preprints in Mathematical Sciences19990101+01:00 Abstract
 The aim of this paper is to extend to Homalgebra structures the theory of formal deformations of algebras which was introduced by Gerstenhaber for associative algebras and extended to Lie algebras by NijenhuisRichardson. We deal with Homassociative and HomLie algebras. We construct the first groups of a deformation cohomology and give several examples of deformations. We provide families of HomLie algebras deforming Lie algebra sl2 and describe as formal deformations the
qdeformed Witt algebra and Jackson sl2.
