btw. the figures with eigensolutions of your equation would be a nice addition to the Examples wiki!
Yes, absolutely. I am learning for my exam tomorrow from Lie groups,
I hated algebra and groups especially... :) Now it's getting better as I am mildly aware of some actual applications.
but I hope to work on this tomorrow after the exam. I need to import my own mesh and then I'll hopefully get the correct eigenvalues. If I do, then I'll write a test for it and put it into examples.
