These lectures are intended for Mathematicians interested in the applications of stochatic methods to modern finance. They will also allow practitioners from financial institutions and companies operating in ASEAN countries to get in touch with European researchers in the subject. This School is part of the Imamis program : we especially encourage people involved in this program or researchers, teachers, or practitioners who want to contribute to the dissemination of Imamis to apply and ask for support both from their home institution and from Cimpa/Imamis.
