Resumen de varphi-Dialgebras and a Class of Matrix "Coquecigrues"

Fausto Ongay

• Starting with the Leibniz algebra defined by a varphi-dialgebra, we construct examples of "coquecigrues," in the sense of Loday, that is to say, manifolds whose tangent structure at a distinguished point coincides with that of the Leibniz algebra. We discuss some possible implications and generalizations of this construction.
