Non-Archimedean Preferences Over Countable Lotteries
We prove a representation theorem for preference relations over countably infinite lotteries that satisfy a generalized form of the Independence axiom, without assuming Continuity. The representing space consists of lexicographically ordered transfinite sequences of bounded real numbers. This result is generalized to preference orders on abstract superconvex spaces
Examples of k-iterated spreading models
It is shown that for every and every spreading sequence
that generates a uniformly convex Banach space ,
there exists a uniformly convex Banach space admitting
as a -iterated spreading model, but not as a
-iterated one.Comment: 16 pages, no figure
