Infinite Matrix Operators and -Frames in Hilbert Spaces
Hassan Hedayati Rad, Tayebe Lal Shateri
The concept of an -frame, recently introduced in frame theory, is obtained by applying an infinite invertible complex matrix to a sequence of elements of a Hilbert space $\mathc…
E-frames multipliers
Hassan Hedayatirad, Tayebe Lal Shateri
-frames are a new generalization for the concept of frames for , where is an infinite invertible complex matrix mapping on …
Controlled -frames in Hilbert spaces
H. Hedayatirad, T. L. Shateri
In the present paper, we introduce the notion of controlled -frames. Then we investigate and study some properties of them and characterize all controlled -duals associated w…
--frames
H. Hedayatirad, T. L. Shateri
In the present paper, we introduce the notion of --frames for a separable Hilbert spaces , where is an invertible infinite matrix mapping on the Hilbert space…
On -frames in Hilbert spaces
H. Hedayatirad, T. L. Shateri
In this paper, we have stated some results about this concept. Furthermore, we introduce the notion of controlled -frames and we characterize all controlled -duals associated…
Some fixed point theorems for multi-valued mappings on partial cone metric spaces
T. L. Shateri, H. Isik
In this paper, we study the fixed point theory for multi-valued mappings on partial cone metric spaces. We prove an analogous to the well-known Kannan fixed point theorem and C…
