On further strengthened Hardy-Hilbert's inequality

International Journal of Mathematics and Mathematical Sciences, 2004
We obtain an inequality for the weight coefficient ω(q,n) (q>1, 1/q+1/q=1, n∈ℕ) in the form ω(q,n)=:∑m=1∞(1/(m+n))(n/m)1 ...

Longitudinal associations between violence exposure and adolescent conduct problems in a high‐adversity, South African setting

Journal of Child Psychology and Psychiatry, Volume 67, Issue 8, Page 1244-1253, August 2026.
Background Violence exposure is a well‐established risk factor for adolescent conduct problems, yet longitudinal research in high‐adversity, low‐ and middle‐income countries (LMICs) remains limited. This study investigated whether early adolescent violence exposure predicts concurrent and longer‐term conduct problems, and explored potential ...

Perspectives on Dynamic Hardy–Littlewood Inequalities in Time Scale Analysis

Mathematics
This study demonstrates several novel dynamic inequalities of the Hardy and Littlewood types on time scales. As special cases, our studies include Hardy’s integral inequalities and Hardy and Littlewood’s discrete inequalities.

On new strengthened Hardy-Hilbert's inequality

International Journal of Mathematics and Mathematical Sciences, 1998
In this paper, a new inequality for the weight coefficient ω(q,n) in the form ω(q,n):=∑m=1∞1m+n(nm)1/q              1,1p+1q=1,n∈N) is proved. This is followed by a strengthened version ofthe Hardy-Hilbert inequality.

The Hardy inequality : about its history and some related results

, 2007
The Hardy inequality has a fascinating past and will have (hopefully) also a fascinating future. Here, the authors present some important steps of the development of the classical Hardy inequality , of its early weighted generalizations (i.e.

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

The Bulletin of the Ecological Society of America, Volume 107, Issue 3, July 2026.
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

On the best constants of Hardy inequality in Rn−k×(R+)k and related improvements

, 2012
We compute the explicit sharp constants of Hardy inequalities in the cone Rk+n:=Rn−k×(R+)k={(x1,…,xn)|xn−k+1>0,…,xn>0} with 1⩽k⩽n. Furthermore, the spherical harmonic decomposition is given for a function u∈C0∞(Rk+n).
