Power vector inequalities for operator pairs in Hilbert spaces and their applications
This study explores the power vector inequalities for a pair of operators (B,C)\left(B,C) in a Hilbert space. By utilizing a Mitrinović-Pečarić-Fink-type inequality for inner products and norms, we derive various power vector inequalities.

Tetris Tight Frames Construction via Hadamard Matrices
We present a new method to construct unit norm tight frames by applying altered Hadamard matrices. Also we determine an elementary construction which can be used to produce a unit norm frame with prescribed spectrum of frame operator.

Compact Weighted Composition Operators and Multiplication Operators between Hardy Spaces
We estimate the essential norm of a compact weighted composition operator 𝑢𝐶𝜑 acting between different Hardy spaces of the unit ball in ℂ𝑁. Also we will discuss a compact multiplication operator between Hardy spaces.

Arλ3(λ1,λ2,Ω)-Weighted Inequalities with Lipschitz and BMO Norms
We first define a new kind of Arλ3(λ1,λ2,Ω) two-weight, then obtain some two-weight integral inequalities with Lipschitz norm and BMO norm for Green's operator applied to differential forms.

Norm derivatives on spaces of operators
We say the norm is Frechet differentiable at x if the convergence to the limit in (1.1) is uniform for all y~X. Norm derivatives of the spaces: LP(dy), 1 ~ p N oo, and C(X) space of real continuous functions on a compact Hausdorff space X have been studied extensively, see for example page 171 in [5].
