Multiple Capture of an Evader in the Linear Pursuit Problem on Time Scales

The linear problem of pursuing one evader by a group of pursuers is considered in a finite-dimensional Euclidean space.In a given time scale, the problem is described by a linear system with a simple matrix. The set of admissible controls for eachparticipant is the unit ball centered at the origin. The terminal sets are given convex compact sets. The pursuers use counter-strategiesbased on information about the initial positions and control prehistory of the evader. Sufficient conditions for the capture of the evaderby a given number of pursuers are obtained in terms of the initial positions and parameters of the game. Sufficient evasion conditions areobtained for discrete time scales.
