Link Download full text Abstract We investigate the existence of pairs (λ, u), with λ > 0 and u harmonic function in a bounded domain Ω ⊂ R3, such that the nonlinear boundary condition ∂u = λ μ sinh u holds on ∂Ω, where μ is a non negative weight function. This type of exponential boundary condition arises in corrosion modeling (Butler Volmer condition).
