Enveloping Algebras of Hom-lie Algebras
A Hom-Lie algebra is a triple (L, [−,−], α), where α is a linear self-map, in which the skew-symmetric bracket satisfies an α-twisted variant of the Jacobi identity, called the Hom-Jacobi identity. When α is the identity map, the Hom-Jacobi identity reduces to the usual Jacobi identity, and L is a Lie algebra. Hom-Lie algebras and related algebras were introduced in [1] to construct deformation...
متن کاملPrimeness of the Enveloping Algebra of the Special Lie Superalgebras
A primeness criterion due to Bell is shown to apply to the universal enveloping algebra of the Cartan type Lie superal-gebras S(V) and e S(V ; t) when dim V is even. This together with other recent papers yields Theorem. Let L be a nite-dimensional simple Lie superalgebra over an algebraically closed eld of characteristic zero. Then L satisses Bell's criterion (so that U(L) is prime), unless L ...
متن کاملGröbner-Shirshov Bases for Lie Superalgebras and Their Universal Enveloping Algebras
We show that a set of monic polynomials in the free Lie superalgebra is a Gröbner-Shirshov basis for a Lie superalgebra if and only if it is a Gröbner-Shirshov basis for its universal enveloping algebra. We investigate the structure of GröbnerShirshov bases for Kac-Moody superalgebras and give explicit constructions of Gröbner-Shirshov bases for classical Lie superalgebras. Supported in part by...
متن کاملDelta Methods in Enveloping Algebras of Lie Colour Algebras
In recent papers J. Bergen and D. S. Passman have applied so-called`Delta methods' to enveloping algebras of Lie superalgebras. This paper generalizes their results to the class of Lie colour algebras. The methods and results in this paper are very similar to those of Bergen and Passman, and many of their proofs generalize easily. However, at some points there are serious diiculties to overcome...
متن کاملThe Isomorphism Problem for Universal Enveloping Algebras of Lie Algebras
Let L be a Lie algebra with universal enveloping algebra U(L). We prove that if H is another Lie algebra with the property that U(L) ∼= U(H) then certain invariants of L are inherited by H. For example, we prove that if L is nilpotent then H is nilpotent with the same class as L. We also prove that if L is nilpotent of class at most two then L is isomorphic to H.
