Hom-type algebras, in particular Hom-Lie algebras, have attracted quite.much attention in recent years. A Hom-Lie algebra is called involutive if its Hom map is.multiplicative and involutive. In this paper, we obtain an explicit construction of the free.involutive Hom-associative algebra on a Hom-module. We then apply this construction.to obtain the universal enveloping algebra of an involutive Hom-Lie algebra. Finally we.generalize the well-known Poincar´e-Birkho-Witt theorem for enveloping algebras of.Lie algebras to involutive Hom-Lie algebras.
