Lipschitz p-Approximate Schauder Frames
K. Mahesh Krishna, P. Sam Johnson
With the aim of representing subsets of Banach spaces as an infinite series using Lipschitz functions, we study a variant of metric frames which we call Lipschitz p-approximate Sch…
Controlled continuous -frames and their duals in Hilbert spaces
Mohamed Rossafi, Fakhr-dine Nhari, P. Sam Johnson
In this paper, we characterize and study the concept of controlled continuous -frame which is an extension of continuous -frame in Hilbert spaces. We introduce the concept of…
Reverse Order Law for Closed Range Operators in Hilbert Spaces
Athira Satheesh K., K. Kamaraj, P. Sam Johnson
We present more than 50 results including some range inclusion results to characterize reverse order law for Moore-Penrose inverse of closed range Hilbert space operators. We use b…
P-Operators on Hilbert Spaces
Rashid A., P. Sam Johnson
A real square matrix is called a P-matrix if all its principal minors are positive. Using the sign non-reversal property of matrices, the notion of P-matrix has been recently e…
Operator-Valued p-Approximate Schauder Frames
K. Mahesh Krishna, P. Sam Johnson
We give an operator-algebraic treatment of theory of p-approximate Schuader frames which includes the theory of operator-valued frames by Kaftal, Larson, and Zhang [\textit{Trans.…
