A system of vectors in a Hilbert space \(H\) is a Riesz basis for \(H\) if there is an automorphism of \(H\) carrying the system onto an orthonormal basis for \(H\). The paper under review presents several results which involve Riesz bases either in themselves or in their proofs (or both). The first theorem, proved independently by \textit{M. Horvath} [

The paper concerns frame multipliers when one of the involved sequences is a Riesz basis. We determine the cases when the multiplier is well defined and invertible, well defined and not invertible, respectively not well defined.
