Polynomial differential equations with piecwise linear coefficients
Mohamad Ali Alwash
Cubic and quartic non-autonomous differential equations with continuous piecewise linear coefficients are considered. The main concern is to find the maximum possible multiplicity…

Polynomial Differential Equations with Small coefficients
M. A. M. Alwash
Classes of polynomial differential equations of degree n are considered. An explicit upper bound on the size of the coefficients are given which implies that each equation in the c…

Periodic Solutions of Abel Differential Equations
M. A. M. Alwash
For a class of polynomial non-autonomous differential equations of degree n, we use phase plane analysis to show that each equation in this class has n periodic solutions. The resu…
