报告摘要:

We consider the 1-d simple symmetric random walk (SSRW) on integers with a penalty if the range of the walk is small. Let  be the n steps of a SSRW and the Hamiltonian is defined by ,where  is the number of sites occupied by S. Let

 and

where  is a positive constant representing the self-repellence strength. Under the measure , we shall present the central limit theorem and large deviation principle of  as n tends to infinity. The continuous analogue with replaced by  (is  the Wiener suasage of radius one) is also considered. The advantage of  this model over Edwards model is that the Wiener suasage is de_ned in  any dimension and the asymptotic behavior of Wiener suasage is  available.
