Problems with mean curvature-like operators and three-point boundary conditions
Dionicio Pastor Dallos Santos
In this paper we study the existence of solutions for a new class of nonlinear differential equations with three-point boundary conditions. Existence of solutions are obtained by u…
Problems with mixed boundary conditions in Banach spaces
Dionicio Pastor Dallos Santos
Using Leray-Schauder degree or degree for -condensing maps we obtain the existence of at least one solution for the boundary value problem of the type \[ \left\{\begin{array}{ll…
Existence of solutions for some nonlinear problems with boundary value conditions
Dionicio Pastor Dallos Santos
In this paper we study the existence of solutions for nonlinear boundary value problems (ϕ(u' ))' = f(t,u,u'), l(u,u')=0 where l(u,u') =0 denotes the Dirichlet or mixed conditions…
Problems with classic homeomorphisms and three-point boundary conditions
Dionicio Pastor Dallos Santos
Using Leray-Schauder degree theory we study the existence of at least one solution for the boundary value problem of the type (φ(u' ))' = f(t,u,u'), u'(0)=u(0), u'(T)= bu'(0), wher…
