Functionals of Multidimensional Diffusions with Applications to Finance

This research monograph provides an introduction to tractable multidimensional diffusion models. It also offers an introduction to the use of Lie symmetry group methods for diffusions, which allows to compute a wide range of functionals.

Provides the reader in a systematic way with the ability to derive explicit formulas for functionals of multidimensional diffusions Special unique chapters on Lie symmetry group methods and matrix valued Wishart processes Provides the most recent introduction to the benchmark approach to finance pioneered by Platen and co-authors The reader finds readily applicable exact simulation methods for various multidimensional diffusion processes?
