Universal coverings of Lie tori (A finite presentation)

Abstract

Using the well-known recognition and structural theorem(s) for root-graded Lie algebras and their universal coverings, we give a finite presentation for the universal covering algebra of a centerless Lie torus of type $X\ne A,C,BC$. We follow a unified approach for the types under consideration.
