This short paper presents an hyperstability theorem for hybrid dynamic systems composed of coupled differential and difference equations subject to time varying nonlinearities satisfying a Popov ' s type inequality . Some corollaries and related physical interpretations are also given.

In this research article, we investigate reverse Radon's inequality, Bergström's the weighted power mean Schlömilch's Bernoulli's inequality and Lyapunov's with Specht's ratio on time scales. We also present Rogers--Holder's logarithmic The scale dynamic inequalities unify extend some continuous their corresponding discrete quantum versions.

In this important work, we discuss some novel Hilbert-type dynamic inequalities on time scales. The investigated here generalize several known scales and unify extend continuous their corresponding discrete analogues. Our results will be proved by using algebraic inequalities, Hölder inequality, Jensen’s inequality

This paper addresses the dynamics of income inequality, both within and across countries. In an endogenous growth model with North-South trade, the dynamics of income inequality depend on the ability of workers to adapt to new technologies, captured by the quality of education. For developing countries with low quality of education, Southern trade liberalization leads to: 1) an overall decline ...
