Abstract: The isotropic position is an important position in the study of extremal problems of convex body. In this paper, the isotropic position of log-concave functions has been studied, and the necessary and sufficient condition of log-concave function which is isotropic been obtained. It is an extension of the necessary and sufficient condition of convex body which is in isotropic position.
