A note on Gaussian integrals over paragrassmann variables

High Energy Physics - Theory 2009-11-07 v1

Abstract

We discuss the generalization of the connection between the determinant of an operator entering a quadratic form and the associated Gaussian path-integral valid for grassmann variables to the paragrassmann case [θp+1=0\theta^{p+1}=0 with p=1p=1 (p>1p>1) for grassmann (paragrassamann) variables]. We show that the q-deformed commutation relations of the paragrassmann variables lead naturally to consider q-deformed quadratic forms related to multiparametric deformations of GL(n) and their corresponding qq-determinants. We suggest a possible application to the study of disordered systems.
