Nontrivial models with indefinite metric
S. Albeverio, H. Gottschalk
The non perturbative construction of quantum field models with nontrivial scattering in arbitrary dimension of the underlying Minkowski space-time is much more simple in the fr…
Representing Euclidean quantum fields as scaling limit of particle systems
S. Albeverio, H. Gottschalk, M. -w. Yoshida
We give a new representation of Euclidean quantum fields as scaling limits of systems of interacting, continuous, classical particles in the grand canonical ensemble.
Partly divisible probability measures on locally compact Abelian groups
S. Albeverio, H. Gottschalk, J. -L. Wu
A notion of admissible probability measures on a locally compact Abelian group (LCA-group) with connected dual group $\hat G=\R^d\times \T^n$ is defined. To such a measure…
Partly Divisible Probability Distributions
S. Albeverio, H. Gottschalk, J. -L. Wu
Given a probability distribution a set of positive real numbers is introduced, so that measures the "divisibility" of . The basic properties of are desc…
Feynman graphs for non-Gaussian measures
S. H. Djah, H. Gottschalk, H. Ouerdiane
Partition- and moment functions for a general (not necessarily Gaussian) functional measure that is perturbed by a Gibbs factor are calculated using generalized Feynman graphs. Fro…
Convoluted generalized white noise, Schwinger functions and their continuation to Wightman functions
S. Albeverio, H. Gottschalk, J. -L. Wu
We construct Euclidean random fields over , by convoluting generalized white noise with some integral kernels , as . We study properties of Schwinger (or m…
