Trefethen Trefethen (2000) discusses techniques for tensor-product geometry, including eigenvalue problems and problems posed on a disk. Both Iserles Iserles (1996) and Morton and Mayers Morton & Mayers (2005) discuss finite differences at curved boundaries and present introductions to the finite element method in two dimensions.
