A preliminary note on Lie g-digroups
摘要
In this paper we introduce the concepts of Lie g-digroups and the affine g-digroup for a Lie g-digroup. Some properties are studied and geometrical aspects of the actions of sub g-digroups of the affine g-digroup are established like in the Lie group case. Moreover, we use infinitesimal action of Lie algebras to determine whether the tangent space to a bar-unit in a g-digroup has a Leibniz algebra structure.
