Massless scalar field in two-dimensional de Sitter universe
Marco Bertola, Francesco Corbetta, Ugo Moschella
We study the massless minimally coupled scalar field on a two--dimensional de Sitter space-time in the setting of axiomatic quantum field theory. We construct the invariant Wightma…
Self-Similar Random Processes and Infinite-Dimensional Configuration Spaces
Gerald A. Goldin, Ugo Moschella, Takao Sakuraba
We discuss various infinite-dimensional configuration spaces that carry measures quasiinvariant under compactly-supported diffeomorphisms of a manifold M corresponding to a physica…
Fourier analysis and holomorphic decomposition on the one-sheeted hyperboloid
Jacques Bros, Ugo Moschella
We prove a Cauchy-type integral representation for classes of functions holomorphic in four priviledged tuboid domains of the complexified one-sheeted two-dimensional hyperboloid.…
