Abstract (EN):
Optimal control problems arise, in which we expect optimal trajectories to
be discontinuous. This might correspond, in an economics context, to consequences of lumped purchases of capital or instantaneous extraction of a
resource [e.g,, Clark, Clarke and Munro (1979)]. Such problems are also
encountered in aerospace applications where corrections to a space vehicle's
trajectory is effected by a rapid fuel burn [e.g., Lawden (1963)].
Considerable progress has been made towards a general theory applicable to
these problems [e.g., Murray (1983), Rishel (1965), Rockafellar (1981) and
Warga (1972, pp. 372-395)]. We announce necessary conditions for optimality,
proved under hypotheses considerably weaker than those previously required.
