Abstract
Let be a separable Hilbert space. In this paper we establish a generalization of Walnut's representation and Janssen's representation of the valued Gabor frame operator on valued weighted amalgam spaces , . Also we show that the frame operator is invertible on , , if the window function is in the Wiener amalgam space . Further, we obtain the Walnut representation and invertibility of the frame operator corresponding to Gabor superframes and multi-window Gabor frames on , as a special case by choosing the appropriate Hilbert space .
