On some lacunary difference sequence spaces defined by a sequence of Orlicz functions and q-lacunary Δnm-statistical convergence

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this article, we introduce the lacunary difference sequence spaces w0(M, θ, Δnm, p, q), w1(M, θ, Δnm, p, q) and w∞(M, θ, Δnm, p, q) using a sequence M = (Mk) of Orlicz functions and investigate some relevant properties of these spaces. Then, we define

Weighted $\beta\gamma$-summability of fuzzy functions of order $\theta$

open access: yes, 2016
The concept of weighted $\beta\gamma$ - summability of order $\theta$ in case of fuzzy functions is introduced and classified into ordinary and absolute sense. Several inclusion relations among the sets are investigated.

Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

The pointwise convergence of Fourier Series (I). On a conjecture of Konyagin [PDF]

open access: yes, 2016
We provide a near-complete classification of the Lorentz spaces $\Lambda_{\varphi}$ for which the sequence $\{S_{n}\}_{n\in \mathbb{N}}$ of partial Fourier sums is almost everywhere convergent along lacunary subsequences. Moreover, under mild assumptions

DFT Study of Halide‐Free Mechanism of the CO2 Cycloaddition onto Epoxide by [PW11O39{Zn(H2O)}]5−: Evidences for the Formation of Hydrogencarbonate Intermediates

open access: yesChemCatChem, Volume 17, Issue 15, August 7, 2025.
The computational study, sustained by experimental data, of the catalytic activity of [PW11O39{Zn(H2O)}]5− in CO2 cycloaddition to epoxide highlights how the carbonic anhydrase‐like character of this complex couples to the versatile binding properties of the polyoxometalate in this reaction pathway. Abstract The intertwined experimental and theoretical

Operator Ideal of Cesaro Type Sequence Spaces Involving Lacunary Sequence [PDF]

open access: yesAbstract and Applied Analysis, 2014
The aim of this paper is to give the sufficient conditions on the sequence spaceCesθ,pdefined in Lim (1977) such that the class of all bounded linear operators between any arbitrary Banach spaces withnth approximation numbers of the bounded linear operators inCesθ,pform an operator ideal.

Highly Shielded Peroxo‐Cerium(IV)‐Containing Polyoxometalate: Synthesis, Structure, and Oxidative Studies

open access: yesChemistryEurope, Volume 3, Issue 4, July 14, 2025.
The peroxo‐di‐cerium(IV)‐di‐lithium‐containing 32‐tungsto‐4‐phosphate [(CeIV2O2)Li2(P2W16O59)2]16− (Ce2Li2P4W32) is synthesized and structurally characterized. This peroxo‐polyanion demonstrates remarkable stability in solution across a broad pH range.

Multidimensional Asymptotically Lacunary Statistical Equivalent of Order α for Sequences of Fuzzy Numbers

open access: yesFuzzy Information and Engineering, 2022
The main goal of this article is to present the notion of double asymptotically lacunary statistical equivalent of order α for sequences of fuzzy numbers by considering fuzzy numbers and Pringsheim limit.
