Instantons and condensates in two-dimensional CPsup(n-1) models
Description
We discuss the respective role of instantons and of vacuum expectation values of local operators in the structure of the Borel transform of CP2sup(n-1) models and suggest an IR finite definition for the contribution of instantons. The structure of the operator product expansion, the renomalization of composite operators, the role of the theta parameter and the significance of semi-classical results are discussed from that point of view.
