High-frequency

Applying GMRES to Helmholtz equation with strong trapping: how does the number of iterations depend on the frequency?
New frequency-explicit bounds on the norms of both the regularised combined field integral equation and its inverse. And first frequency-explicit error bound on the h-BEM for the Helmholtz exterior Neumann problem with a standart second-kind formulation.
