Vv. Filippov, ON THE THEORY OF THE CAUCHY-PROBLEM FOR AN ORDINARY DIFFERENTIAL-EQUATION WITH DISCONTINUOUS RIGHT-HAND SIDE, Sbornik. Mathematics, 83(2), 1995, pp. 383-403
An apparatus is developed for proving theorems on the existence of a s
olution of the Cauchy problem and on continuous dependence of solution
s on the initial conditions and parameters, applicable to situations n
ot covered by known results on this subject.
