Grigorenko, N. L. A pursuit problem in many person differential games. (Russian) Zbl 0662.90107 Mat. Sb., N. Ser. 135(177), No. 1, 36-45 (1988). A general differential game for m pursuers and two evadors is described (the problem formulation follows L. S. Pontryagin); pursuers’ strategies have the form \(u_ i(t)=V_ i(t,v_ 1(t),v_ 2(t))\) where \(v_ 1(t)\) and \(v_ 2(t)\) are controls of the evadors. Capture of the j-th evador at time \(t_ j\) implies \(z_{ij}(t_ j)\in M_{ij}(t_ j)\) for some \(i\leq m\); here \(z_{ij}\) is a state of a system describing the interaction process for the i-th pursuer and the j-th evador, \(M_{ij}(t)=M^ 1_{ij}+M^ 2_{ij}(t)\), \(M^ 1_{ij}\) are linear subspaces, \(M^ 2_{ij}(t)\) are convex compact functions continuous in t. System equations linear in \(z_{ij}\) are considered. Sufficient algebraic conditions for two evadors to be captured within a finite time interval are given, and an upper bound for the capture time is deduced. For the case of three pursuers \(\dot x{}_ i=u_ i(t)\), \(\| u_ i(t)\| \leq 1\), and two evadors \(\dot y{}_ j=v_ j(t)\), \(\| v_ j(t)\| \leq 1\), it is shown that for any initial position three situations are possible: (a) ensured evasion, (b) capture of one evador, (c) capture of one prescribed evador.
