%0 Journal Article %T FUSION FRAMES AND G-FRAMES IN TENSOR PRODUCT AND DIRECT SUM OF HILBERT SPACES %A Amir Khosravi %A M. Mirzaee Azandaryani %J Applicable Analysis and Discrete Mathematics %D 2012 %I University of Belgrade and Academic Mind %R 10.2298/aadm120619014k %X In this paper we study fusion frames and g-frames for the tensor products and direct sums of Hilbert spaces. We show that the tensor product of a finite number of g-frames (resp. fusion frames, g-Riesz bases) is a g-frame (resp. fusion frame, g-Riesz basis) for the tensor product space and vice versa. Moreover we obtain some important results in tensor products and direct sums of g-frames, fusion frames, resolutions of the identity and duals. %K Fusion frames %K g-frames %K tensor products %K direct sums %U http://pefmath.etf.rs/vol6num2/AADM-Vol6-No2-287-303.pdf
