On the Polynomial Solutions of the Polynomial Differential Equations y y ' = a(0)(x) plus a(1)(x) y plus a(2)(x) y(2) + horizontal ellipsis plus a(n)(x) y(n)
In this paper we deal with differential equations of the form yy ' = P(x, y) where y ' = dy/dx and P(x, y) is a polynomial in the variables x and y of degree n in the variable y. We provide an upper bound for the number ...
Asymptotic behaviour of solutions to linear neutral delay differential equations with periodic coefficients
(American Institute of Mathematical SciencesSpringfield, 2014-05)
We study the asymptotic behaviour of the solutions of a class of
linear neutral delay differential equations with discrete delay where the coeffi-
cients of the non neutral part are periodic functions which are rational ...
Existence results for abstract impulsive second-order neutral functional differential equations
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
We establish the existence of mild solutions for a class of impulsive second-order partial neutral functional differential equations with infinite delay in a Banach space. (C) 2009 Published by Elsevier Ltd

Rational first integrals of the liénard equations: The solution to the poincaré problem for the liénard equations
(2021-01-01)
Poincaré in 1891 asked about the necessary and sufficient conditions in order to characterize when a polynomial differential system in the plane has a rational first integral. Here we solve this question for the class of ...
