Central Limit Theorem for the Edwards Model
نویسندگان
چکیده
The Edwards model in one dimension is a transformed path measure for standard Brownian motion discouraging self-intersections. We prove a central limit theorem for the endpoint of the path, extending a law of large numbers proved by Westwater (1984). The scaled variance is characterized in terms of the largest eigenvalue of a one-parameter family of differential operators, introduced and analyzed in van der Hofstad and den Hollander (1994). Interestingly, the scaled variance turns out to be independent of the strength of self-repellence and to be strictly smaller than one. AMS 1991 subject classifications. 60F05, 60J55, 60J65.

The Local Limit Theorem: A Historical Perspective
The local limit theorem describes how the density of a sum of random variables follows the normal curve. However the local limit theorem is often seen as a curiosity of no particular importance when compared with the central limit theorem. Nevertheless the local limit theorem came first and is in fact associated with the foundation of probability theory by Blaise Pascal and Pierre de Fer...
متن کاملCentral Limit Theorem in Multitype Branching Random Walk
A discrete time multitype (p-type) branching random walk on the real line R is considered. The positions of the j-type individuals in the n-th generation form a point process. The asymptotic behavior of these point processes, when the generation size tends to infinity, is studied. The central limit theorem is proved.
متن کاملDensity Estimators for Truncated Dependent Data
In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...
متن کاملThe Constants in the Clt for the Edwards Model
The Edwards model in one dimension is a transformed path measure for one-dimensional Brownian motion discouraging self-intersections. In van der Hofstad, den Hollander and KK onig (preprint 1995) a central limit theorem (CLT) is proved for the uctuations of the endpoint of the path around its linear asymptotics. In the present paper, we study the constants appearing in this CLT (which represent...
