Dirichlet-to-Neumann operator on the perturbed unit disk
This article concerns the Laplacian on a perturbed unit disk $Omega_epsilon={ z=rexp(iheta): r <1+epsilon f(heta) }$, with dynamical boundary condition whose solution can be represented by a Dirichlet-to-Neumann semigroup. By neglecting the terms of order $epsilon^2$, we obtain a simple e...
