Abstract
We compute the orderparameter function q(x) for the Sherrington-Kirkpatrick spin-glass to high accuracy near T = Tc in zero external field. The free energy is calculated to order (Tc - T)7. The overlap function dx/dq is parabolic near q = 0. We show generally that q(x) involves only odd powers of x below its plateau. Hence the overlap distribution in strictly zero field is symmetric with continuous derivatives at q = 0Keywords
