%0 Journal Article %T Hom-Lie admissible Hom-coalgebras and Hom-Hopf algebras %A Abdenacer Makhlouf %A Sergei Silvestrov %J Mathematics %D 2007 %I arXiv %X The aim of this paper is to generalize the concept of Lie-admissible coalgebra introduced by Goze and Remm to Hom-coalgebras and to introduce Hom-Hopf algebras with some properties. These structures are based on the Hom-algebra structures introduced by the authors. %U http://arxiv.org/abs/0709.2413v2
