Modulus of continuity of operator functions [PDF]
St. Petersburg Mathematical Journal, 2009 Summary: Let \(A\) and \(B\) be bounded selfadjoint operators on a separable Hilbert space, and let \(f\) be a continuous function defined on an interval \( [a,b]\) containing the spectra of \(A\) and \(B\). If \(\omega _f\) denotes the modulus of continuity of \(f\), then \[ \| f(A)-f(B)\| \leq 4\Big[\log\Big(\frac{b-a}{\| A-B\|}+1\Big)+1\Big]^2 \cdot

On generalized difference sequence spaces of fuzzy numbers - doi: 10.4025/actascitechnol.v35i1.15566
Acta Scientiarum: Technology, 2013 The idea of difference sequence space was introduced by Kizmaz (1981) and this concept was generalized by Tripathy and Esi (2006). In this article we introduced the paranormed sequence spaces cF(f,Λ,Δm,p), (f,Λ,Δm,p) and (f,Λ,Δm,p) of fuzzy numbers ...

Cumhuriyet Science Journal, 2023 Let f be any modulus function. We prove that the classes of strongly deferred Cesàro convergent sequences defined by f and deferred statistical convergent sequences are equivalent if the sequence is f-deferred uniformly integrable.

Strongly $(\eta ,\omega )$-convex functions with nonnegative modulus [PDF]
Journal of Inequalities and Applications, 2020 AbstractWe introduce a new class of functions called strongly $(\eta,\omega)$(η,ω)-convex functions. This class of functions generalizes some recently introduced notions of convexity, namely, the η-convex functions and strongly η-convex functions. We also establish inequalities of the Hermite–Hadamard–Fejér’s type, which generalize results of Delavar ...

Effect of Pore Geometry on the Compressibility of a Confined Simple Fluid
, 2018 Fluids confined in nanopores exhibit properties different from the properties of the same fluids in bulk, among these properties are the isothermal compressibility or elastic modulus.

Strongly (Vλ,A,P) ‐ summable sequence spaces defined by a modulus
Mathematical Modelling and Analysis, 2007 We introduce the strongly (Vλ,A,p) ‐ summable sequences and give the relation between the spaces of strongly (Vλ,A,p) ‐ summable sequences and strongly (Vλ,A,p) ‐ summable sequences with respect to a modulus function when A = (α ik ) is an infinite ...

The minimal growth of entire functions with given zeros along unbounded sets
Математичні Студії, 2020 Let $l$ be a continuous function on $\mathbb{R}$ increasing to $+\infty$, and $\varphi$ be a positive function on $\mathbb{R}$. We proved that the condition $$ \varliminf_{x\to+\infty}\frac{\varphi(\ln[x])}{\ln x}>0 $$ is necessary and sufficient in ...

Extremal non-BPS black holes and entropy extremization
, 2006 At the horizon, a static extremal black hole solution in N=2 supergravity in four dimensions is determined by a set of so-called attractor equations which, in the absence of higher-curvature interactions, can be derived as extremization conditions for ...
