Multiple solutions for a Neumann boundary value problem.

2003
Summary: The aim of this note is to establish a multiplicity result for the ordinary Neumann problem \[ -u''+ uh(u')=\lambda f(t,u)h(u'),\;u'(a)= u'(b)= 0. \] The approach is based on a critical point theorem.

Multiplicity of Solutions to a Boundary-Value Problem with Nonlinear Neumann Condition

Journal of Mathematical Sciences, 2005
Summary: We consider the boundary-value problem \[ \begin{aligned} -\Delta_p u + | u| ^{p-2} u =& 0\quad \text{in\;} B_R,\\ | \nabla u| ^{p-2}\langle\nabla u;n\rangle =& | u| ^{q-2} u\quad \text{on\;}S_R,\end{aligned} \] where \(\Delta_p u = \text{div}(| \nabla u| ^{p-2} \nabla u)\) and \(n\) is the unit outward normal. We show that there exist so many

Interpolation of Boundary Value Problems of Neumann Type on Smooth Domains

Journal of the London Mathematical Society, 1992
Summary: Consider the Sobolev space \(W^ N_{p {\mathcal B}}\) of all functions with up to \(N\) derivatives in \(L_ p\) (on a smooth domain) satisfying a set \({\mathcal B}\) of homogeneous boundary conditions. Then the real interpolation spaces between \(L_ p\) and \(W^ N_{p {\mathcal B}}\) are characterized completely in the case \(1 < p < \infty\).

Successively iterative method of nonlinear Neumann boundary value problems

Applied Mathematics and Computation, 2010
This paper proves the existence of nontrivial sign changing solutions to a class of nonlinear second-order Neumann boundary value problems, through an iterative technique that uses an increasing operator fixed point theorem. This is a theoretical study and no numerics are given.
