A nonlocal concave-convex problem with nonlocal mixed boundary data
2016, Abdellaoui, Boumediene, Dieb, Abdelrazek, Valdinoci, Enrico
The aim of this paper is to study a nonlocal equation with mixed Neumann and Dirichlet external conditions. We prove existence, nonexistence and multiplicity of positive energy solutions and analyze the interaction between the concave-convex nonlinearity and the Dirichlet-Neumann data.
Parabolic equations with dynamical boundary conditions and source terms on interfaces
2012, Elst, A.F.M. ter, Meyries, Martin, Rehberg, Joachim
We consider parabolic equations with mixed boundary conditions and domain inhomogeneities supported on a lower dimensional hypersurface, enforcing a jump in the conormal derivative. Only minimal regularity assumptions on the domain and the coefficients are imposed. It is shown that the corresponding linear operator enjoys maximal parabolic regularity in a suitable Lp-setting. The linear results suffice to treat also the corresponding nondegenerate quasilinear problems.
