We analyse the nonlinear supersymmetric model associated with the Polyakov Euclidean σ-model. In this theory the main point is to be able to compute the partition and correlation functions of interesting statistical variables. We briefly review some tools for renormalizing the partition function and we carry out the computations of the n-instanton contributions for a toy model on S<sup>1</sup>; these are given explicitly in terms of specific hypergeometric functions.
