Therefore, the Picard theorem implies that, for each 0 < [epsilon] < 1, there exists a unique solution [S.sub.[epsilon]](t) [member of] [C.sup.1] (0, [T.sub.[epsilon]];[X.sup.m]) for a fixed time [T.sub.[epsilon]] > 0.
To use the Picard theorem on [H.sup.m] space (m > 5/2), we first obtain that F is Lipschitz continuous on [H.sup.m], i.e.,

The "Hyperbolically imbedded in Y" is a very important property because it implies many properties, such as the finiteness of integral points (as we have mentioned in the Lang's conjecture), extension properties (big Picard theorems), etc.
