G-frames in tensor product of Hilbert spaces

Frames in a Hilbert space are sequences that have basis-like properties but which need not be bases. It is shown that gframes are generalizations of frames. Tensor product is useful in the approximation of univariate ones. In this paper, we prove that tensor product of g-frames is a g-frame and also if they are tight, Riesz bases or orthonormal, then so is theirtensor product.
