Multiple positive solutions of a singular Gelfand type problem for second-order impulsive differential systems
The authors prove the existence of multiple positive solutions for a singular Gelfand-type boundary value problem for second-order impulsive differential systems with real multiparameters. Furthermore, they study existence and multiplicity of positive radial solutions for semilinear elliptic systems on an annulus or an exterior domain with suitable impulse conditions. Proofs are mainly employed by the upper and lower solutions method for systems and the fixed-point index arguments.
