在过去的20年里,对于任意多项式f(h)∈ C [h]的广义Heisenberg代数H(f)被用来解释各种物理系统和许多物理现象。本文首先给出了H(f)的中心,以及两个H(f)同构的充分必要条件。然后,对于任何多项式f(h)∈ C [h],我们确定H(f)上的所有有限维单模。更准确地说,它们有三类:A H(f)′(λ,z stec,a),B H(f)′(λ,z stec,a)和C H(f)(z stec,n)。如果f= wh + c,对任意c∈ C和n(n> 1)个单位原根w,我们实际上得到了H(f)上所有不可约模的完全分类。
Generalized Heisenberg algebras H (f) for any polynomial f (h)∈ C [h] have been used to explain various physical systems and many physical phenomena for the last 20 years. In this paper, we first obtain the center of H (f), and the necessary and sufficient conditions on f for two H (f) to be isomorphic. Then we determine all finite dimensional simple modules over H (f) for any polynomial f (h)∈ C [h]. More precisely, there are three classes of them, A H (f)′(λ, z˙, a), B H (f)′(λ, z˙, a), and C H (f)(z˙, n). If f= w h+ c for any c∈ C and n-th (n> 1) primitive root w of unity we actually obtain a complete classification of all irreducible modules over H (f).
