Abstract In this paper, the existence of positive periodic solutions is studied for Liénard equation with a singularity of repulsive type, x ″ ( t ) + f ( x ( t ) ) x ′ ( t ) + φ ( t ) x μ ( t ) − 1 x γ ( t ) = e ( t ) , $$ x''(t)+f(x(t))x'

This paper introduces a new concept of dual periodic boundary conditions. One of these conditions relates to the endpoints of an interval, while the other one involves two nonlocal positions within the interval. Under these boundary conditions, we es

Abstract The novelty of this paper is that, based on Mawhin’s continuation theorem, we present some sufficient conditions that ensure that there is at least one solution to a particular kind of a boundary value problem with the p-Laplacian and gene

Abstract In this paper, we study the existence and uniqueness of a periodic solution for a third-order neutral delay differential equation (NDDE) by applying Mawhin’s continuation theorem of coincidence degree and analysis techniques. An illustrati
