SUMMARY:Solution of Singular Differential Games by Gradient Methods
DESCRIPTION:Lecturer:Oleg Kelis\n Faculty:Department of Mathematics\n Insti
 tute:University of Haifa\n Location:Classroom 165\, ground floor\, Library
 \, Aerospace Eng.\n Zoom: \n Abstract: \n Details: \n In this study we foc
 us on a zero-sum linear-quadratic differential game. One of the main feat
 ures of such a game is that the weight matrix of the minimizer’s control
  cost in the cost functional is singular. Due to this singularity\, the g
 ame cannot be solved either by applying the Isaacs Min-Max principle\, [1
 ]\, or the Bellman-Isaacs equation approach\, [2]. In [3] such a game was 
 analyzed with so-called regularization approach in the case where the wei
 ghting matrix of the minimizer’s control cost equals zero. In [4]\, the
  game was studied and analyzed in which the weight matrix of the minimi
 zer’s control cost has appropriate diagonal singular form also using t
 he regularization approach. In the present work we introduce a slightly mo
 re general case of the weight matrix of the minimizer’s control cost th
 an in [4]. This means that only a part of coordinates of the minimizer’
 s control is singular\, while the rest of coordinates are regular. As app
 lication we introduce a pursuit-evasion differential game and we propose 
 two gradient methods\, the Arrow-Hurwicz-Uzawa and the Korpelevich method
 s\, for solving this game. We present numerical illustrations demonstrati
 ng the iterative procedures performances.\n
