Various authors have invoked discretized fractional Brownian motion (fBm) as a model for chain polymers with long-range interaction of monomers along the chain. We show that for these, in contrast to the Brownian case, linear forces are acting betwee

The topics discussed in this book can be classified into three parts:(i) Gaussian processes. The most general and in fact final representation theory of Gaussian processes is included in this book. This theory is still referred to often and its devel

In this paper, we investigate the potential for a class of non-Gaussian processes so-called generalized grey Brownian motion. We obtain a closed analytic form for the potential as an integral of the M-Wright functions and the Green function. In parti

In this paper we introduce and study three classes of fractional periodic processes. An application to ring polymers is investigated. We obtain a closed analytic expressions for the form factors, the Debye functions and their asymptotic decay. The re

In this article we present recent results in our ongoing study for weakly self-avoiding fractional processes leading to polymer models. In particular we sketch the results for stars and loops. For fractional random walks we give an explicit formula f

We prove that there exists a diffusion process whose invariant measure is the fractional polymer or Edwards measure for fractional Brownian motion, $\mu_{ {g,H}}$ , $H\in (0,1)$ for $dH < 1$ . The diffusion is constructed in the framework of Dirichle

For certain Sheffer sequences ( s n ) n = 0 ∞ on C , Grabiner (1988) proved that, for each α ∈ [ 0 , 1 ] , the corresponding Sheffer operator z n ↦ s n ( z ) extends to a linear self-homeomorphism of E min α ( C ) , the Frechet topological sp
