Class Notes M1 Mathematics, 2011-2012 MM26E Numerical Approximation of PDEs

Hervé Le Dret

These notes describe the material that will be covered in class, except for the first chapter due to the first three classes missed. I will post the chapters based on the progression in class.

Just in case, here is a link to notes of a M1 class I taught in the past, that include more detail on such basic tools in analysis as convolution, distributions and so on: Outils de base en analyse appliquée. These notes are in French.
