On singularly weighted generalized Laplacian systems and their applications

Advances in Nonlinear Analysis, 2018
We study the homogeneous Dirichlet boundary value problem of generalized Laplacian systems with a singular weight which may not be integrable. Some explicit intervals which correspond to the existence and nonexistence of positive solutions for the system

Existence of positive periodic solutions of second-order differential equations with weak singularities

Boundary Value Problems, 2014
We establish the existence of positive periodic solutions of the second-order differential equation x″+a(t)x=f(t,x)+c(t) via Schauder’s fixed point theorem, where a∈L1(R/TZ;R+), c∈L1(R/TZ;R), f is a Caratheodory function and it is singular at x=0.

Existence and multiplicity of positive solutions for multiparameter periodic systems

Open Mathematics
We deal with the existence and multiplicity of positive solutions for differential systems depending on two parameters, λ1,λ2{\lambda }_{1},{\lambda }_{2}, subjected to periodic boundary conditions.

New criteria for the existence of non-trivial fixed points in cones

, 2013
We give new criteria for the existence of nontrivial fixed points on cones assuming some monotonicity of the operator on a suitable conical shell. Moreover, we give an application to the existence of multiple solutions for a nonlocal boundary value ...
