Using maximization theorem, the author presented the existence of Nash equilibrium in generalized games, and in these results, the strategy set is noncompact and has infinite players [2].
However, for noncompact G' and for infinite-dimensional [pi], the restriction [pi][|.sub.G'] is not always a direct sum of irreducible representations, see [5, 6] for details.
Recall that time-like geodesics (as [l.sub.0]) are compact in Ad[S.sup.2+1] and noncompact in d[S.sup.2+1], while spacelike ones (as [l.sub.i], [l'.sub.i]) are compact in d[S.sup.2+1] but noncompact in Ad[S.sup.2+1].

It is consistent with ZFC that there exists a countably compact noncompact space X such that [bar.D] has countable network for any discrete set D [subset] [C.sub.p](X).

Another interesting research direction is to present the problem using a noncompact formulation based on the idea of compatible sets (see [11, 17]) that allows for an indirect consideration of an infinite number of time slots.
