Abstract:Let g be a complex simple Lie algebra of type B 2 and q be a nonzero complex number which is not a root of unity. In the classical case, a theorem of Dixmier asserts that the simple factor algebras of Gelfand-Kirillov dimension 2 of the positive part U + (g) of the enveloping algebra of g are isomorphic to the first Weyl algebra. In order to obtain some new quantized analogues of the first Weyl algebra, we explicitly describe the prime and primitive spectra of the positive part U + q (g) of the quantized envel… Show more
A classification of the simple weight modules is given for the (6-dimensional) Euclidean Lie algebra e(3) = sl 2 ⋉ V 3 . As an intermediate step, a classification of all simple modules is given for the centralizer C of the Cartan element H (in the universal enveloping algebra U = U(e(3))). Generators and defining relations for the algebra C are found (there are three quadratic relations and one cubic relation). The algebra C is a Noetherian domain of Gelfand-Kirillov dimension 5. Classifications of prime, primitive, completely prime, and maximal ideals are given for the algebra U. Published by AIP Publishing. [http://dx

“…Let K be a field and q ∈ K * = K \ {0} not a root of unity. In [10], primitive factor algebras of Gelfand-Kirillov dimension 2 of the positive part U + q (so 5 ) of the quantized enveloping algebra U q (so 5 ) were classified and can be thought of as quantum analogues of the first Weyl algebra. Among those are A.P.…”

Previously, the fact that every endomorphism of a quantum generalized Weyl algebra A(a(h), q) is an automorphism, has only been established, by Richard, in the case where a(h) is a (Laurent) monomial [11].…”
Abstract. We prove that every endomorphism of a simple quantum generalized Weyl algebra A over a commutative Laurent polynomial ring in one variable is an automorphism. This is achieved by obtaining an explicit classification of all endomorphisms of A. Our main result applies to minimal primitive factors of the quantized enveloping algebra U q (sl 2 ) and certain minimal primitive quotients of the positive part of U q (so 5 ).Mathematics Subject Classification (2010). 16W35, 16S32, 16W20, 17B37.
“…The prime or/and primitive ideals of various quantum algebras (and their classification) are considered in [15,16,21,24,25,26,27,34,37,39,43]. The automorphism group of some (quantum) algebras are considered in [1,2,13,22,32,35,36,44].…”
For the algebra A in the title, its prime, primitive and maximal spectra are classified. The group of automorphisms of A is determined. The simple unfaithful A-modules and the simple weight A-modules are classified.
