The definitions of generalized directional derivative and generalized gradient of Lipschitz functions defined on Riemannian manifold are presented. Some properties of the directional derivative and gradient are proved by using tangent and cotangent mapping. The minimization necessary condition of nonsmooth Lipschitz functions is given. Moreover, Fritz John necessary optimality condition in mathematical programming is provided on Riemannian manifold.

We first introduced a new concept called transitive resolvable idempotent symmetric quasigroup, proved that the necessary condition for the existence of TRISQ is also sufficient, then presented a tripling construction for LKTS by using TRISQ instead of TKTS, thus removed the condition "there exists a TKTS" in Denniston''s tripling construction for LKTS; We also improved J. Lei''s product construction for LKTS by removing the condition "there exists a TKTS".
