Abstract

Let H=(H1,H2)\mathbb{H}=(H_{1},H_{2}) be a Hopf brace in a symmetric monoidal category C{\sf C}. In this article it is proved that the category of modules over H\mathbb{H} is isomorphic to the category of modules over the smash product algebra H1H2H_{1}\sharp H_{2}. Furthermore, the category of modules over H\mathbb{H} in the sense of Zhu is characterized by the condition that a certain action lies in the cocommutativity class of H2H_{2}.
