Quantum Mechanical Propagators in Terms of Hida Distributions
We review some basic notions and results of White Noise Analysis that are
used in the construction of the Feynman integrand as a generalized White Noise
functional. After sketching this construction for a large class of potentials
we show that the resulting Feynman integrals solve the Schroedinger equation
Self-avoiding fractional Brownian motion - The Edwards model
In this work we extend Varadhan's construction of the Edwards polymer model
to the case of fractional Brownian motions in , for any dimension , with arbitrary Hurst parameters .Comment: 14 page
Integral Representation of Generalized Grey Brownian Motion
In this paper we investigate the representation of a class of non Gaussian
processes, namely generalized grey Brownian motion, in terms of a weighted
integral of a stochastic process which is a solution of a certain stochastic
differential equation. In particular the underlying process can be seen as a
non Gaussian extension of the Ornstein-Uhlenbeck process, hence generalizing
the representation results of Muravlev as well as Harms and Stefanovits to the
non Gaussian case.Comment: arXiv admin note: text overlap with arXiv:1708.06784,
