Strong singularities of attractive and repulsive type to 2n-order neutral differential equation
Keyword(s):
Abstract This paper is devoted to the existence of a positive periodic solution for a kind of 2n-order neutral differential equation with a singularity, where nonlinear term $g(t,x)$ g ( t , x ) has strong singularities of attractive and repulsive type at the origin. Our proof is based on coincidence degree theory.
