Abstract

We introduce a QQ-operator Qz\mathcal{Q}_z for the hyperbolic Calogero--Moser system as a one-parameter family of explicit integral operators. We establish the standard properties of a QQ-operator, i.e.~invariance of Hamiltonians, commutativity for different parameter values and that its eigenvalues satisfy an explicitly given first order ordinary difference equation in the parameter zz.
