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 g-frames are generalizations of frames. 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 their tensor product.
