On the oscillation of certain third-order difference equations
(Springer Nature, 2005-01-01)
We establish some new criteria for the oscillation of third-order difference equations of the form Delta((1/a(2)(n))(Delta(1/a(1)(n))(Delta x(n))(alpha 1))(alpha 2)) + delta q(n)f(x[g(n)]) = 0, where Delta is the forward ...

Discrete focal boundary-value problems
(Cambridge University Press (CUP), 2000-02-01)
In this paper we shall employ the nonlinear alternative of Leray-Schauder and known sign properties of a related Green's function to establish the existence results for the nth-order discrete focal boundary-value 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.
