Duality and alpha-duality of g-frames and fusion frames in Hilbert spaces

In this paper, we get some results about alpha-duals of g-frames and fusion frames in Hilbert spaces. Especially, the direct sums and tensor products for alpha-duals of g-frames and fusion frames are considered and some of the obtained results for duals are generalized to alpha-duals.
