Theory of q-commuting contractions : joint reducing subspaces and orthogonal decompositions

Functional Analysis 2024-07-30 v3

Abstract

In the literature, we have several results associated with canonical decomposition of commuting contractions. In this paper, we generalize a few of these results to QQ-commuting contractions. Here we mainly deal with QQ-commuting and doubly QQ-commuting contractions when QQ is a family of unitary operators.
