We present an acceleration technique, effective for explicit finite difference schemes
describing diffusive processes with nearly symmetric operators, called Super-Time-
Stepping (STS). The technique is applied to the ...
A scaled self-decomposable stochastic process put forward by Carr, Geman, Madan
and Yor (2007) is used to model long term equity returns and options prices. This
parsimonious model is compared to a number of other ...
