An inequality for the Steklov spectral zeta function of a planar domain

, 2018
We consider the zeta function  for the Dirichlet–to–Neumann operator of a simply connected planar domain  bounded by a smooth closed curve. We prove that, for a xed real s satisfying jsj > 1 and xed length L.@/ of the boundary curve, the zeta function
