Singularities of the minimum time function for semilinear parabolic systems
Dipartimento di Matematica, Università di Roma "Tor Vergata" Via della Ricerca Scientifica, 00133 Roma, Italy Fax: 6-72594699
The time optimal control problem for a semilinear parabolic systems is here studied. The singular points of the Minimum Time function are characterized as the initial point of multiple time-optimal trajectories. Moreover, an example is given to show how such singularities may develop.
