Construction of a self-adjoint dilatation for a problem with impedance boundary condition
B. S. Pavlov, M. D. Faddeev
Abstract:
We study the spectral problem
$$
\Delta u+k^2u=0,\quad\dfrac{\partial u}{\partial n}-ik\sigma u|_{\delta\Omega}=0,\quad\sigma\geqslant0.
$$
We construct a self-adjoint dilatation and the problem is reduced to the investigation of a dissipative operator in a space with energy metric.
