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. -
Existence criteria for singular initial value problems with sign changing nonlinearities
(Hindawi Limited, 2001-01-01)A general existence theory is presented for initial value problems where our nonlinearity may be singular in its dependent variable and may also change sign. -
