Boundary value problems for discrete equations
(Elsevier BV, 1997-07-01)Two existence results are presented for second-order discrete boundary value problems. The first result is based on the notion of upper and lower solutions and the second result is based on the discrete Gelfand problem. -
Eigenvalues and the one-dimensional p-laplacian

Fixed-point theorems for nonlinear operators with singular perturbations and applications
(Springer Nature, 2014-01-01)In this paper, using fixed-point index theory and approximation techniques, we consider the existence and multiplicity of fixed points of some nonlinear operators with singular perturbation. As an application we consider ... -

Singular differential equations with linear and nonlinear boundary conditions
(Elsevier BV, 1998-02-01)Existence results are established for the singular equation y " + f(t, y) = 0, where f is not a Caratheodory function. Our nonlinearity f is allowed to change sign. -
Unbounded positive solutions for second order singular boundary value problems with derivative dependence on infinite intervals
(Division of Functional Equations, The Mathematical Society of Japan (JST), 2008-01-01)The existence of at least one unbounded positive solution and the existence of multiple unbounded positive solutions are established for the singular second-order boundary value problem p(t)(-1)(p(t)x'(t))' + Phi(t)f(t,x,px') ...
