Abstract

The quantum Cayley-Hamilton theorem for the generator of the reflection equation algebra has been proven by Pyatov and Saponov, with explicit formulas for the coefficients in the Cayley-Hamilton formula. However, these formulas do not give an \emph{easy} way to compute these coefficients. Jordan and White provided an elegant formula for the coefficients given with respect to the generators of the reflection equation algebra. In this paper, we provide Cauchy-Binet formulas for these coefficients with respect to generators of Oq,QR(MN(C))\mathcal{O}_{q,Q}^{\mathbb{R}}(M_{N}(\mathbb{C})), the multiparameter quantized ^{*}-algebra of functions on MN(C)M_{N}(\mathbb{C}) as a real variety, which contains the reflection equation algebra as a subalgebra. We also prove a Cauchy-Binet formula for the inverse of a matrix involving these generators.
