A geometric interpretation of the transition density of a symmetric Lévy Process

N. Jacob, V. Knopova, S. Landwehr +1

We study for a class of symmetric Lévy processes with state space $\rn$ the transition density $p_{t} (x)$ in terms of two one-parameter families of metrics, $(d_{t})_{t > 0}$ and $(δ_t)_…

Feller Semigroups Obtained by Variable Order Subordination

Kristian P. Evans, Niels Jacob

For certain classes of negative definite symbols $q (x, ξ)$ and state space dependent Bernstein function $f (x, s)$ we prove that $- p (x, D)$ , the pseudo-differential operator with symbo…

Some thoughts on multiparameter stochastic processes

Niels Jacob, Alexander Potrykus

We suggest to investigate certain non-standard (pseudo-)differential operators in order to construct and to study multi-parameter processes. Our approach will include "classical" m…
