Computer Simulations of Self-Repelling Fractional Brownian Motion
Abstract
Self-repelling fractional Brownian motion (fBm) has been constructed, generalizing the Edwards model for the conformations of chain polymers. In this context of particular interest is the predicted scaling behaviour of their end-to-end length, i.e. the anomalous diffusion of self-repelling fBm. We briefly present the model and a heuristic formula of the scaling behaviour for general dimension and Hurst index, and then our computer simulations of self-repelling fBm paths, their method and first results.
