Reproducing subgroups of $Sp(2,\mathbb{R})$. Part I: algebraic classification

Group Theory 2015-11-03 v2 Functional Analysis

Abstract

We classify the connected Lie subgroups of the symplectic group Sp(2,R)Sp(2,\mathbb{R}) whose elements are matrices in block lower triangular form. The classification is up to conjugation within Sp(2,R)Sp(2,\mathbb{R}). Their study is motivated by the need of a unified approach to continuous 2D signal analyses, as those provided by wavelets and shearlets.
