  3. 2. Pricing of American options with discrete dividends using a PDE and a volatility surface while calculating derivatives with automatic differentiation

    Master-uppsats, Linköpings universitet/Produktionsekonomi

    Författare :David Hjelmberg; Björn Lagerström; [2014]
    Nyckelord :American options; BSM PDE; discrete dividends; forward PDE; local volatility surface; automatic differentiation;
