Abstract: The topic of discussion will be A-infinity, L-infinity and Com-infinity algebras and morphisms between them, which are up to homotopy versions of associative, Lie and commutative algebraic structures., respectively. While A-infinity and L-infinity algebras are widely used, Com-infinity ones are less common and a convenient for use description of this structure is based on the Lie cooperad. So, I will start by describing a convenient for use description of the Lie cooperad.
