Periodic orbit action correlations are studied forthe piecewise linear, area-preserving Baker map.Semiclassical periodic orbit formulae together withuniversal spectral statistics in the correspondingquantum Baker map suggest the existence of universalperiodic orbit correlations. The calculation of periodicorbit sums for the Baker map can be performed withthe help of a Perron-Frobenius type operator. Thismakes it possible to study periodic orbit correlationsfor orbits with period up to 500 iterations of themap. Periodic orbit correlations are found to agreequantitatively with the predictions from randommatrix theory up to a critical length determined by thesemiclassical error. Exponentially increasing termsdominate the correlations for longer orbits which aredue to the violation of unitarity in the semiclassicalapproximation.
