@AsafKaragila: Milne forgot to add explanatory notes to the 11th tip. German is not a bad languague for expressing mathematics.

comment Intertwiner in german?
I had done just that before posting the question, but I would have liked to have a single word translation rather than 9 syllables. - Would the term ''äquivariante Abbildung'' also be appropriate for intertwiners between representations of an algebra?

comment Infinite-dimensional translation-invariant measure
I am interested in an infinite-dimensional space with a definite inner product but not necessarily closed in the corresponding topology. Thus it need not be a Hilbert space.

comment classical solutions of PDE with mixed boundary conditions
Thanks. I hadn't realize before that the pure Neumann case is in Gilbarg/Trudinger which I generally know quite well. I still hope to get info on the mixed case from somewhere....

comment Special solution of Helmholtz equation
But doesn't the differential equation have to hold only in the interior? Wouldn't your statment just mean that the second derivative cannot be continous at the corners?
