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. ...

Fixed point theory for generalized contractions on spaces with two metrics

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.
Positive solutions of singular problems with sign changing carathéodory nonlinearities depending on x′

A leray-schauder alternative for weakly-strongly sequentially continuous weakly compact maps
(Springer Nature, 2005-01-01)
A new applicable Leray-Schauder alternative is presented for weakly-strongly sequentially continuous maps. This result is then used to establish a general existence principle for operator equations.
