Abstract: In
this paper, by using the fixed points of strict-set-contractions, we study the
existence of at least one or two positive solutions to the nonlinear four-point
boundary value problem
in
Banach space E, where q is zero element of E, with As an application, we also give one
example to demonstrate our results.
Keywords and phrases: Banach space, positive solution, fixed point, four-point boundary value problem.
