Lacunary Sets and Function Spaces with Finite Cotype

Journal of Functional Analysis, 2002
Let \(G\) be an infinite metrizable compact Abelian group and let \(\Gamma\) be its dual group. Let \(U(G)\subseteq C(G)\) denote the space of functions with uniformly convergent Fourier series. For an Orlicz function~\(\psi\) let \(L^\psi\) denote the Orlicz space associated to~\(\psi\).

Some New Lacunary Strong Convergent Vector-Valued Sequence Spaces

Abstract and Applied Analysis, 2014
We introduce some vector-valued sequence spaces defined by a Musielak-Orlicz function and the concepts of lacunary convergence and strong (A)-convergence, where A=(aik) is an infinite matrix of complex numbers.

Exploring the Impact of In Ovo Injection of Flavonoid‐Based Aromatase Inhibitors on Gonadal Histology Differentiation in Ross 308 Broiler Chickens

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study aimed to evaluate the in ovo injection of nettle extract, mushroom extract and their mixture as natural anti‐aromatase on sex reversal, histological changes in ovaries and testes and carcass characteristics of Ross 308 broiler chickens. Sex differentiation in avian species A completely randomized block design used to allocate 500 fertilized ...

On Metric Ramsey-type Dichotomies

, 2002
The classical Ramsey theorem, states that every graph contains either a large clique or a large independent set. Here we investigate similar dichotomic phenomena in the context of finite metric spaces.

Lacunary differentiability of functions in

Journal of Approximation Theory, 1984
AbstractThe existence of directional derivatives of functions in the Sobolev spaces Lpk(Rn) is studied. The novelty consists in calculating them through lacunary incremental quotients. Under these conditions no restrictions on p are necessary; the condition p > (nk) can be dropped.

The dimension of well approximable numbers

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract In this survey article, we explore a central theme in Diophantine approximation inspired by a celebrated result of Besicovitch on the Hausdorff dimension of well approximable real numbers. We outline some of the key developments stemming from Besicovitch's result, with a focus on the mass transference principle, ubiquity and Diophantine ...

Lacunary recurrences for Eisenstein series

, 2015
Using results from the theory of modular forms, we reprove and extend a result of Romik about lacunary recurrence relations for Eisenstein series.Comment: 6 pages, more detailed proofs in v3, accepted for publication in Research in Number ...
