“…Frame theory literature became richer through several generalizations, namely, G-frame (generalized frames) [3], K-frame (frames for operators (atomic systems)) [4], fusion frame (frames of subspaces) ( [5,6]), K-fusion frame (atomic subspaces) [7], etc. and some spin-off applications by means of Gabor analysis in ( [8,9]), dynamical system in mathematical physics in [10], nature of shift invariant spaces on the Heisenberg group in [11], characterizations of discrete wavelet frames in C N in [12], extensions of dual wavelet frames in [13], constructions of disc wavelets in [14], orthogonality of frames on locally compact abelian groups in [15] and many more.…”
