Hadamard Multipliers and Abel Dual of Hardy Spaces

open access: yesJournal of Function Spaces, 2016
The paper is devoted to the study of Hadamard multipliers of functions from the abstract Hardy classes generated by rearrangement invariant spaces. In particular the relation between the existence of such multiplier and the boundedness of the appropriate

Decomposition of Hardy–Morrey spaces

open access: yes, 2009
In this paper, we establish the decompositions of Hardy–Morrey spaces in terms of atoms concentrated on dyadic cubes, which have the same cancellation properties of the classical Hardy ...

‘Fish in simulated water’? A Bourdieusian analysis of Chinese doctoral students' learning experiences in Southeast Asian developing countries

open access: yesBritish Educational Research Journal, EarlyView.
Abstract International student mobility (ISM) has historically followed a pattern of movement from developing regions to developed countries. However, in recent years, there has been a noticeable increase in the number of Chinese students pursuing doctoral studies in Southeast Asian developing countries, an area that has received relatively little ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Some Generalized Hardy Spaces

open access: yes, 1967
This paper is concerned with generalizations of the classical Hardy spaces (8, p. 39) and the question of boundary values for functions of these various spaces.

Bridging the Gap: Student Voices on Recruitment and Retention in Ecology

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Students entering ecology and environmental science face a variety of challenges, including limited awareness of career paths, lack of mentorship, and difficulties connecting with peers and faculty. These challenges are often amplified for students from marginalized backgrounds, who may also encounter microaggressions, underrepresentation, and

Weighted multilinear p-adic Hardy operators and commutators

open access: yesOpen Mathematics, 2017
In this paper, the weighted multilinear p-adic Hardy operators are introduced, and their sharp bounds are obtained on the product of p-adic Lebesgue spaces, and the product of p-adic central Morrey spaces, the product of p-adic Morrey spaces ...

On some spaces of holomorphic functions of exponential growth on a half-plane

open access: yesConcrete Operators, 2016
In this paper we study spaces of holomorphic functions on the right half-plane R, that we denote by Mpω, whose growth conditions are given in terms of a translation invariant measure ω on the closed half-plane R.

Sharp Bounds for Fractional Conjugate Hardy Operator on Higher-Dimensional Product Spaces

open access: yesJournal of Function Spaces, 2020
In this paper, we obtain the sharp bound for fractional conjugate Hardy operator on higher-dimensional product spaces from L1ℝn1×⋯×ℝnm to the space wLQℝn1×⋯×ℝnm and Lpℝn1×⋯×ℝnm to the space Lqℝn1×⋯×ℝnm. More generally, the operator norm of the fractional
