A New Reverse Extended Hardy–Hilbert’s Inequality with Two Partial Sums and Parameters
Axioms, 2023 By using the methods of real analysis and the mid-value theorem, we introduce some lemmas and obtain a new reverse extended Hardy–Hilbert’s inequality with two partial sums and multi-parameters.

Loss of physical reversibility in reversible systems [PDF]
Physica D: Nonlinear Phenomena, 2020 A dynamical system is said to be reversible if, given an output, the input can always be recovered in a well-posed manner. Nevertheless, we argue that reversible systems that have a time-reversal symmetry, such as the Nonlinear Schr{ö}dinger equation and the $ϕ^4$ equation can become "physically irreversible".
