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)
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.
Fixed point theory for self maps between fréchet spaces
