On universal enveloping algebras in a topological setting

, 2014
We establish the exponential law for suitably topologies on spaces of vector-valued smooth functions on topological groups, where smoothness is defined by using differentiability along continuous one-parameter subgroups. As an application, we investigate

Universal Enveloping Algebra

1996
For a complex Lie algebra g, the universal enveloping algebra U(g) is an explicit complex associative algebra with identity having the property that any Lie algebra homomorphism of g into an associative algebra A with identity “extends” to an associative algebra homomorphism of U(g) into A and carrying 1 to 1.

Formality and Deformations of Universal Enveloping Algebras

International Journal of Theoretical Physics, 2007
The main objective of this paper is to describe the universal enveloping algebras of finite dimensional Lie algebras that satisfy the following constraints: their Hochschild complex, seen as differential graded Lie algebra, is quasi-isomorphic to its Hochschild cohomology. This enlarges and completes previous work of the authors [\textit{M.

Noetherian enveloping algebras of simple graded Lie algebras

Journal of the Mathematical Society of Japan
It is shown that if the universal enveloping algebra of a simple $\mathbb Z^n$-graded Lie algebra is Noetherian, then the Lie algebra is finite-dimensional.

Integral bases for the universal enveloping algebras of map superalgebras

, 2013

Some Norms on Universal Enveloping Algebras

Canadian Journal of Mathematics, 1998
AbstractThe universal enveloping algebra,U(𝔤), of a Lie algebra 𝔤 supports some norms and seminorms that have arisen naturally in the context of heat kernel analysis on Lie groups. These norms and seminorms are investigated here from an algebraic viewpoint.

The Universal Enveloping Algebra

2004
We have seen that elements of the Lie algebra of a Lie group G are derivations of C ∞ (G). They are thus first-order differential operators that are left-invariant. The universal enveloping algebra is a purely algebraically defined ring that may be identified with the ring of all left-invariant differential operators, including higher-order ones.

The Universal Enveloping Algebra

1993
As is well known (see §19 of Encycl. Math. Sc. 11) every associative algebra A can be turned into a Lie algebra L(A) by replacing its multiplication (a, b) → ab by the commutator [a, b] = ab — ba. Clearly, every homomorphism of associative algebras is automatically a homomorphism of the corresponding Lie algebras, i.e.
