Given a finite dimensional real inner product space V with a self-dual cone K, an element e in Kâ (the interior of K), and a linear transformation L on V, the value of the linear game (L,e) is defined byv(L,e):=maxxâÎ(e)â¡minyâÎ(e)â¡ãL(x),yã=minyâÎ(e)â¡maxxâÎ(e)â¡ãL(x),yã, where Î(e)={xâK:ãx,eã=1}. In [5], various properties of a linear game and its value were studied and some classical results of Kaplansky [6] and Raghavan [8] were extended to this general setting. In the present paper, we study how the value and properties change as e varies in Kâ. In particular, we study the structure of the set Ω(L) of all e in Kâ for which the game (L,e) is completely mixed and identify certain classes of transformations for which Ω(L) equals Kâ. We also describe necessary and sufficient conditions for a game (L,e) to be completely mixed when v(L,e)=0, thereby generalizing a result of Kaplansky [6].
