Tempered fractional calculus
Fractional derivatives and integrals are convolutions with a power law. Multiplying by an
exponential factor leads to tempered fractional derivatives and integrals. Tempered …

The fractional Poisson process and the inverse stable subordinator
M Meerschaert, E Nane, P Vellaisamy - 2011 - projecteuclid.org
The fractional Poisson process is a renewal process with Mittag-Leffler waiting times. Its
distributions solve a time-fractional analogue of the Kolmogorov forward equation for a …

Characterization of dependence of multidimensional Lévy processes using Lévy copulas
This paper suggests Lévy copulas in order to characterize the dependence among
components of multidimensional Lévy processes. This concept parallels the notion of a …
