We presente a study of graded Leibniz algebras and its universal enveloping Leibniz algebra. We prove that the universal enveloping Leibniz algebra of a finite dimensional graded Leibniz algebra is a quasi-Koszul algebra or an inhomogeneous Koszul algebra. We presented an imersion of the derivation set of a Leibniz algebra with maximum lenght into the set of derivations of its universal enveloping Leibniz algebra to study the first homology group of those wild type associative algebras.
We will follow Loday and Pirashvili's work and Green and Martinez-Villa's works.
