摘要
We generalize the Picard-Lindelof theorem on the unique solvability of initial value problems (x) over dot = f (t, x), x (t(0)) = x(0), by replacing the sufficient classical Lipschitz condition of f with respect to x with a more general Lipschitz condition along hyperspaces of the (t, x)-space. A comparison with known results is provided and the generality of the new criterion is shown by an example.
