Some inequalities for double integrals and applications for cubature formula
Acta Universitatis Sapientiae: Mathematica, 2019 We establish two Ostrowski type inequalities for double integrals of second order partial derivable functions which are bounded. Then, we deduce some inequalities of Hermite-Hadamard type for double integrals of functions whose partial derivatives in ...

Sum of squared logarithms - an inequality relating positive definite matrices and their matrix logarithm [PDF]
, 2013 Let y1,y2,y3,a1,a2,a3∈(0,∞) be such that y1y2y3=a1a2a3 and y1+y2+y3≥a1+a2+a3,y1y2+y2y3+y1y3≥a1a2+a2a3+a1a3. Then (logy1)2+(logy2)2+(logy3)2≥(loga1)2+(loga2)2+(loga3)2. This can also be stated in

Proof of one open inequality of Laub-Ilani type
, 2020 In this paper, we prove one new algebraic trigonometric inequality of Laub-Ilani type. This inequality was posted as the Conjecture 2.4 in the paper A. Y. Özban, “New AlgebraicTrigonometric Inequalities of Laub-Ilani type”, Bull. Aust. Math.

Journal of Ocean Engineering and Science, 2023 This paper presents a study of nonlinear waves in shallow water. The Korteweg-de Vries (KdV) equation has a canonical version based on oceanography theory, the shallow water waves in the oceans, and the internal ion-acoustic waves in plasma.

The best bounds in Gautschi's inequality
, 2000 Different approach to both Gautschi’s inequalities (1) and (2) is given. This results in obtaining the best upper bound in (1) and the best lower bound in (2). The main result is the proof of the convexity of the function [Γ(x+t)/Γ(x+s)]1/(t−s) for |t−s|
