Construction of upper and lower solutions for singular discrete initial and boundary value problems via inequality theory
(Springer Nature, 2005-01-01)We present new existence results for singular discrete initial and boundary value problems. In particular our nonlinearity may be singular in its dependent variable and is allowed to change sign. -
Existence of solutions for a fourth-order boundary value problem on the half-line via critical point theory
(University of Szeged, 2016-01-01)In this paper, a fourth-order boundary value problem on the half-line is considered and existence of solutions is proved using a minimization principle and the mountain pass theorem. -
Impulsive periodic solutions for singular problems via variational methods
(Cambridge University Press (CUP), 2012-02-16)In this paper we study impulsive periodic solutions for second-order nonautonomous singular differential equations. Our proof is based on the mountain pass theorem. Some recent results in the literature are extended. -
