Optimal dual pairs of frames for erasures
S. Arati, P. Devaraj, Shankhadeep Mondal
The study involves characterizations of dual pairs of frames which are optimal to handle erasures among all dual pairs for a finite dimensional Hilbert space. A new optimality meas…

Optimal dual frames and dual pairs for probability modelled erasures using weighted average of operator norm and spectral radius
S. Arati, P. Devaraj, Shankhadeep Mondal
The prime focus of this paper is the study of optimal duals of a given finite frame as well as optimal dual pairs, in the context of probability modelled erasures of frame coeffici…
