Controlled weaving frames in Hilbert spaces
Reza Rezapour, Asghar Rahimi, E. Osgooei +1
In this paper, we first introduce the notion of controlled weaving K-g-frames in Hilbert spaces. Then, we present sufficient conditions for controlled weaving K-g-frames in separab…
Characterizing of Inner Product Spaces by the Mapping
Hossein Dehghan
For the vectors and in a normed linear spaces , the mapping is defined by . In this note, comparing the mappings…
Metric projection and convergence theorems for nonexpansive mappings in Hadamard spaces
Hossein Dehghan, Jamal Rooin
For a nonempty convex subset of a Hadamard space , it is proved that if and only if for all $y\in…
A Characterization of Metric Projection in CAT(0) Spaces
Hossein Dehghan, Jamal Rooin
In this paper, we present a characterization of metric projection in CAT(0) spaces by using the concept of quasilinearization. Furthermore, some basic properties of matric projecti…
Some Monotonicity Properties of Convex Functions with Applications
Jamal Rooin, Hossein Dehghan
We mainly establish a monotonicity property between some special Riemann sums of a convex function on , which in particular yields that $\frac{b-a}{n+1}\sum_{i=0}^n f\le…
A Characterization of Inner Product Spaces Related to the Skew-Angular Distance
Hossein Dehghan
A new refinement of the triangle inequality is presented in normed linear spaces. Moreover, a simple characterization of inner product spaces is obtained by using the skew-angular…
Approximating fixed points of asymptotically nonexpansive mappings in Banach spaces by metric projections
Hossein Dehghan
In this paper, a strong convergence theorem for asymptotically nonexpansive mappings in a uniformly convex and smooth Banach space is proved by using metric projections. This theor…
