Positive solutions of boundary value problems with nonlinear nonlocal boundary conditions [PDF]
Opuscula Mathematica, 2016 We consider the existence of at least three positive solutions of a nonlinear first order problem with a nonlinear nonlocal boundary condition given by \[\begin{aligned} x^{\prime}(t)& = r(t)x(t) + \sum_{i=1}^{m} f_i(t,x(t)), \quad t \in [0,1 ...

Boundary oscillations and nonlinear boundary conditions
Comptes Rendus. Mathématique, 2006 We study how oscillations in the boundary of a domain affect the behavior of solutions of elliptic equations with nonlinear boundary conditions of the type ∂u∂n+g(x,u)=0. We show that there exists a function γ defined on the boundary, that depends on the oscillations at the boundary, such that, if γ is a bounded function, then, for all nonlinearities g,

SOME ELLIPTIC PROBLEMS WITH NONLINEAR BOUNDARY CONDITIONS [PDF]
Spectral Theory and Nonlinear Analysis with Applications to Spatial Ecology, 2005 This paper concerns with some elliptic equations with non-linear boundary conditions. Sub-supersolution and bifurcation methods are used in order to obtain existence, uniqueness or multiplicity of positive solutions.

Reaction-diffusion waves with nonlinear boundary conditions
Networks and Heterogeneous Media, 2013 A reaction-diffusion equation with nonlinear boundary condition is considered in a two-dimensional infinite strip. Existence of waves in the bistable case is proved by the Leray-Schauder method.

A cantilever equation with nonlinear boundary conditions
Electronic Journal of Qualitative Theory of Differential Equations, 2009 We prove new results on the existence of positive solutions for some cantilever equation subject to nonlocal and nonlinear boundary conditions. Our main ingredient is the classical fixed point index.
