On Adjoint Additive Processes
Kristian P. Evans, Niels Jacob
Starting with an additive process , it is in certain cases possible to construct an adjoint process which is itself additive. Moreover, assuming th…
Higher Order Eigenvalues for Non-Local Schrödinger Operators
Niels Jacob, Feng-Yu Wang
Two-sided estimates for higher order eigenvalues are presented for a class of non-local Schrödinger operators by using the jump rate and the growth of the potential. For instance,…
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 in terms of two one-parameter families of metrics, and $(δ_t)_…
Feller Semigroups Obtained by Variable Order Subordination
Kristian P. Evans, Niels Jacob
For certain classes of negative definite symbols and state space dependent Bernstein function we prove that , 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…
