Abstract: We prove new, sharp, wavenumber-explicit bounds on the norms of the Helmholtz single- and double-layer boundary-integral operators as mappings from $${L^2({\partial {\Omega }})}\rightarrow H^1({\partial {\Omega }})$$L2(∂Ω)→H1(∂Ω) (where $${\partial {\Omega }}$$∂Ω is the boundary of the… read more here.

Abstract: Using variational methods, we prove in different situations the existence and multiplicity of solutions for the following Steklov problem: $$\begin{aligned} -\text{ div }(a(x, \nabla u))+|u|^{p(x)-2}u= & {} 0, \quad \text {in }\Omega , \\ a(x,… read more here.
