Abstract This paper considers the existence and multiplicity of fixed points for the integral operator Tu(t)=λ∫0Tk(t,s)f(s,u(s),u′(s),…,u(m)(s))ds,t∈[0,T]≡I, $$ {\mathcal{T}}u(t)=\lambda \int _{0}^{T}k(t,s) f\bigl(s,u(s),u^{\prime }(s), \d

Abstract In this work we obtain sufficient conditions for the existence of bounded solutions of a resonant multipoint second-order boundary value problem, with a fully differential equation. The noninvertibility of the linear part is overcome by a ne

In this paper, we were interested in obtaining the exact expression and studying the regions of constant sign of Green’s function related to a second-order perturbed periodic problem coupled with integral boundary conditions at the extremes of the

In this paper, we obtain the explicit expression of the Green’s function related to a general n-th order differential equation coupled to non-local linear boundary conditions. In such boundary conditions, an n dimensional parameter dependence is al

The paper deals with a singular nonlinear initial value problem with a $\phi$-Laplacian $$ (p(t)\phi(u'(t)))'+ p(t)f(\phi(u(t)))=0,\ t>0, \quad u(0)=u_0 \in [L_0,L],\ u'(0)=0. $$ Here, $f$ is a continuous function with three roots $\phi(L_0)

In this paper, we prove the existence of solutions of nonlinear boundary value problems of arbitrary even order using the lower and upper solutions method. In particular, we point out the fact that the existence of a pair of lower and upper solutions
