Extremal discrepancy behavior of lacunary sequences [PDF]

Monatshefte für Mathematik, 2014
In 1975 Walter Philipp proved the law of the iterated logarithm (LIL) for the discrepancy of lacunary sequences: for any sequence $(n_k)_{k \geq 1}$ satisfying the Hadamard gap condition $n_{k+1} / n_k \geq q > 1,~k \geq 1,$ we have $$ \frac{1}{4 \sqrt{2}} \leq \limsup_{N \to \infty} \frac{N D_N(\{ n_1 x \}, \dots, \{n_N x\})}{\sqrt{2 N \log \log N}}

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

Geochemistry, 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.

Lacunary strong A -convergence sequence spaces defined by a sequence of moduli

Kuwait Journal of Science, 2013
The definition of lacunary strong A-convergence to a modulus is extended to a definition of lacunary strong A -convergence with respect to a sequence of moduli.

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

ChemCatChem, 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

Lacunary Statistical Convergence of Order alpha and Lacunary Strongly Summable Sequences of Order alpha of Generalized Difference Sequences

ITM Web of Conferences, 2018
The notion of the α th order Δim - lacunary statistical convergence and α th order lacunary strongly (Δim, p)-summable sequences was introduced by Altınok et al. [1].

On Some New Sequence Spaces and Statistical Convergence Methods for Double Sequences

Demonstratio Mathematica, 2014
In this paper, we introduce some new double sequence spaces with respect to an Orlicz function and define two new convergence methods related to the concepts of statistical convergence and lacunary statistical convergence for double sequences.

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

ChemistryEurope, 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.

Controlling Lampenflora in Heritage Sites: In Situ Testing of Polyoxometalate–Ionic Liquids in the Pommery Champagne Cellar

ChemPlusChem, Volume 90, Issue 7, July 2025.
The article evaluates polyoxometalate–ionic liquids (POM–ILs) as biocidal agents against lampenflora in the UNESCO‐listed Pommery Champagne cellar. POM–ILs effectively inhibit microbial colonization over one year with minimal visual impact and outperform the commercial biocide Preventol RI80.
