this paper have been written while Florin Panaite was a visiting professor at University of Ferrara
in September 2014, supported by INdAM, and a visiting scholar at the Erwin Schrodinger
Institute in Vienna in July 2014 in the framework of the “Combinatorics, Geometry and Physics”
programme; he would like to thank both these institutions for their warm hospitality.

A BiHom-associative algebra is a (nonassociative) algebra A endowed with two commuting multiplicative linear maps α,β:A→A such that α(a)(bc)=(ab)β(c), for all a,b,c∈A. This concept arose in the study of algebras in so-called group Hom-categories. In this paper, we introduce as well BiHom-Lie algebras (also by using the categorical approach) and BiHom-bialgebras. We discuss these new structures by presenting some basic properties and constructions (representations, twisted tensor products, smash products etc).
