The molecular characterization of anisotropic Herz-type Hardy spaces with two variable exponents

open access: yesOpen Mathematics, 2020
In this article, the authors establish the characterizations of a class of anisotropic Herz-type Hardy spaces with two variable exponents associated with a non-isotropic dilation on ℝn{{\mathbb{R}}}^{n} in terms of molecular decompositions.

A criterion of weak compactness for operators on subspaces of Orlicz spaces

open access: yesJournal of Function Spaces, Volume 6, Issue 3, Page 277-292, 2008., 2008
We give a criterion of weak compactness for the operators on the Morse‐Transue space MΨ, the subspace of the Orlicz space LΨ generated by L∞.

Symmetric Besov-Bessel Spaces

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
In this paper we introduce the symmetric Besov-Bessel spaces. Next, we give a Sonine formula for generalized Bessel functions. Finally, we give a characterization of these spaces using the Bochner-Riesz means.

On the trace space of a Sobolev space with a radial weight

open access: yesJournal of Function Spaces, Volume 6, Issue 3, Page 259-276, 2008., 2008
Our concern in this paper lies with trace spaces for weighted Sobolev spaces, when the weight is a power of the distance to a point at the boundary. For a large range of powers we give a full description of the trace space.

New classes of rearrangement‐invariant spaces appearing in extreme cases of weak interpolation

open access: yesJournal of Function Spaces, Volume 4, Issue 3, Page 275-304, 2006., 2006
We study weak type interpolation for ultrasymmetric spaces L?,E i.e., having the norm ??(t)f*(t)?E˜, where ?(t) is any quasiconcave function and E˜ is arbitrary rearrangement‐invariant space with respect to the measure d t /t. When spaces L?,E are not “too close” to the endpoint spaces of interpolation (in the sense of Boyd), the optimal interpolation ...

Dual complements for domains of ℂ^n

open access: yesMathematical Inequalities & Applications, 2019
Let Ω ⊂ Cn be a bounded, strictly convex domain and ̃ Ω be its dual complement. Very few such domains with fully described dual complements have been known.

Non‐equivalent greedy and almost greedy bases in lp

open access: yesJournal of Function Spaces, Volume 4, Issue 1, Page 25-42, 2006., 2006
For 1 < p < 8 and p ? 2 we construct a family of mutually non‐equivalent greedy bases in lp having the cardinality of the continuum. In fact, no basis from this family is equivalent to a rearranged subsequence of any other basis thereof. We are able to extend this statement to the spaces Lp and H1.

Applications of one inequality to measures of non-compactness and narrow operators

open access: yesMathematical Inequalities & Applications, 2019
We consider a generalization of an inequality from papers by Yu. A. Dubinskii, J.L. Lions and E. Magenes. This inequality is of great importance for the proof of solvability of nonlinear elliptic and parabolic equations. In contrast to their works, we do

Plant Secondary Metabolites as Defense Tools against Herbivores for Sustainable Crop Protection

open access: yesInternational Journal of Molecular Sciences, 2022
Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized to provide defensive functions and regulate defense signaling pathways to safeguard plants ...
