Abstract
The spin-spin correlation functions in the ground state of certain 2D fully frustrated Ising models fall off with distance with exponent eta = 1/2. This is known both numerically and from calculations that are special to each model. This value of the exponent contrasts with eta = 1/4 for the unfrustrated systems at T-c. The purpose of this paper is to develop a common method that is applicable to both frustrated and unfrustrated systems.
