About instability in an elastic Cosserat body with pores

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This article is centered on the study of the isotropic, porous Cosserat elastic media, realized by means of a parallel with the media of the same type, but anisotropic, by following the rewriting in a new form of the equations that govern this theory ...

Ostrowski Type Inequalities Via ψ − (α, β, γ, δ)−Convex Function [PDF]

In this paper, we are introducing very first time the class of ψ − (α, β, γ, δ)−convex function in mixed kind, which is the generalization of many classes of convex functions. We would like to state well-known Ostrowski inequality via Montgomery identity

On the metrizability of suprametric space

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
The question of metrizability of suprametric space is answered positively. The observed metric coincides with a suprametric in a way that convergence and continuity are preserved between suprametric space and associated metric space along with the ...

New norm and numerical radius bounds for accretive-dissipative operator matrices

Special Matrices
In operator and matrix theory, obtaining sharper bounds for quantities such as the operator norm and the numerical radius is of central importance. The main goal of this paper is to present new novel bounds that work for the norm and numerical radius of ...

A Lower Bound for the Differences of Powers of Linear Operators

, 2008
Let T be a bounded linear operator in a Banach space, with σ(T) = {1}. In 1983, Esterle–Berkani ’ s conjecture was proposed for the decay of differences (I − T) T n as follows: Either lim infn→ ∞ (n + 1) (I − T) T n ≥ 1/e or T = I.

Weak convergence theorems for inertial Krasnoselskii-Mann iterations in the class of enriched nonexpansive operators in Hilbert spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we present some results about the aproximation of fixed points of nonexpansive and enriched nonexpansive operators. In order to approximate the fixed points of enriched nonexpansive mappings, we use the Krasnoselskii-Mann iteration for ...

Further inequalities for convex functions with applications to matrix inequalities

Demonstratio Mathematica
Building on the ideas and techniques from a recent paper by D.Q. Huy et al. [Linear Algebra Appl. 656 (2023), 368–384], we establish new inequalities for convex and log-convex functions.

On the Properties for Iteration of a Compact Operator with Unstructured Perturbation

, 1996
. We consider certain speed estimates for Krylov subspace methods (such as GMRES) when applied upon systems consisting of a compact operator K with small unstructured perturbation B.
