Introduction to scilab and computer implementation : Introduction 1st class
Short Program : it may be slighty modified/updated along the course. The section and chapter numbers are always given
with respect to Brenner-Scott.
1st class :
0. Quick presentation of the course.
1. Derivation of diffusion or heat equation from discrete jump processes
: first the simple brownian case and then non homogeneous diffusion with
sources.
2. Elliptic problems introduced as stationary solutions or asymptotic in
time of diffusion problems. Formal proof based on the energy dissipation for the asymptotic
in time.
3. Other examples without full derivation : Black and Scholes for
finance, fluid mechanics (Navier-Stokes only).
