On structure of homogenenous Wick ideals in Wick $\ast$-algebras with braided coefficients

Abstract

We study the structure of Wick homogenenous ideals of higher degrees in quadratic algebras allowing Wick ordering. We present a method how to construct a homogeneous Wick ideal ${\mathcal{I}}_{n+1}$ of degree $n+1$ out of a homogeneous Wick ideal ${\mathcal{I}}_n$ of degree $n$ so that ${\mathcal{I}}_{n+1}\subset {\mathcal{I}}_n$. We show that in some particular cases our procedure allows one to get a description of the largest homogeneous Wick ideals of higher degrees having generators of the largest quadratic Wick ideal only. Finally we study classes of $\ast$-representations of Wick version of CCR annihilating certain homogeneous Wick ideals of degree higher than $2$.
