Abstract

In a previous paper (Juntunen and Stenberg in Math Comput 78:1353–1374, 2009) we have extended Nitsche’s method (in: Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg 1970/71) for the Poisson equation with general Robin boundary conditions. The analysis required that the solution is in \(H^{s}\), with \(s>3/2\). Here we give an improved error analysis using a technique proposed by Gudi (Math Comput 79:2169–2189 2010).
