Completeness of SoV Representation for $\mathrm{SL}(2,\mathbb{R})$ Spin Chains

Abstract

This work develops a new method, based on the use of Gustafson's integrals and on the evaluation of singular integrals, allowing one to establish the unitarity of the separation of variables transform for infinite-dimensional representations of rank one quantum integrable models. We examine in detail the case of the $\mathrm{SL}(2,\mathbb{R})$ spin chains.
