J-fusion frame for Krein spaces

Shibashis Karmakar

In this article we introduce the notion of $J$ -fusion frame for a Krein space $K$ . We relate this new concept with fusion frames for Hilbert spaces and also with $J$ -frame…

J-Frame Sequences in Krein Space

Shibashis Karmakar, SK. Monowar Hossein, Kallol Paul

Let ${f_{n} : n \in N}$ be a $J$ -frame for a Krein space $K$ and $P_{M}$ be a $J$ -orthogonal projection from $K$ onto a subspace $M$ . In…

Frames on Krein Spaces

Shibashis Karmakar, Sk Monowar Hossein

In this article we define frame for a Krein space K with a J-orthonormal basis and extend the notion of frame sequence and frame potential analogous to Hilbert spaces.We show that…
