Positive solutions for (p,n−p) conjugate boundary value problems
(Elsevier BV, 1998-12-01)
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. ...
Some new results for singular problems with sign changing nonlinearities
(Elsevier BV, 2000-01-01)
Twin solutions to singular dirichlet problems
(Elsevier BV, 1999-12-01)
Eigenvalues and the one-dimensional p-laplacian
(Elsevier BV, 2002-02-01)
A note on the existence of multiple fixed points for multivalued maps with applications
(Elsevier BV, 2000-01-01)
Existence criteria for operator inclusions in abstract spaces
(Elsevier BV, 2000-01-01)
Some nonoscillation criteria for inclusions
(Cambridge University Press (CUP), 2006-02-01)
New nonoscillatory criteria are presented for second order differential inclusions. The theory relies on Ky Fan's fixed point theorem for upper semicontinuous multifunctions.
