On spectrally optimal duals for r-erasures of frames generated by graphs
Deepshikha, Aniruddha Samanta
In [9], authors studied spectrally optimal dual frames for 1-erasure and 2-erasures of frames generated by graph. In this paper, we study spectrally optimal dual frames for r-erasu…

On spectrally optimal duals of frames generated by graphs
Deepshikha, Aniruddha Samanta
Recently, the concept of frames generated by graphs has been introduced in \cite{D}. In this paper, we study spectrally optimal dual frames of frames generated by graphs. We show t…

Frames generated by graphs
Deepshikha
Frames are the most natural generalization of orthonormal bases that allow the inclusion of redundant systems. In this article, we introduce the concept of frames generated by grap…
