Universal enveloping algebra of a pair of compatible Lie brackets

Rings and Algebras 2023-09-01 v3

Abstract

Applying the Poincare-Birkhoff-Witt property and the Groebner-Shirshov bases technique, we find the linear basis of the associative universal enveloping algebra in the sense of V. Ginzburg and M. Kapranov of a pair of compatible Lie brackets. We state that the growth rate of this universal enveloping over nn-dimensional compatible Lie algebra equals n+1n+1.
