The Floquet theory for linear periodic differential equations pertains to equations with continuous right-hand side. In the present paper we generalize this theory to systems with discontinuous ...

In this paper, the existence of positive periodic solutions to two compete predator-one smith growth for prey model governed by difference equations with ratio-dependent and periodic coefficients is ...

We study the classical linear partial differential equations: Poisson's equation and the heat equation. We learn about representation formulas for solutions, maximum principles, and energy estimates.
