Does anybody know how to interpret the sentence: For any set $T$ of mixed strategies, let $D[T]$ denote the set of probability distributions over the elements of $T$, each expressed as vector, conformable to a mixed strategy, that gives the ultimate distribution of pure strategies.
This sentence appeared at p.139 of the paper
Crawford, V.P. Equilibrium without independence, Journal of Economic Theory 50 (1990), 127-154.
The pdf is available online (just google).
In particular, what I really don't understand is the last part: What's the meaning of being conformable to a mixed strategy? More seriously: what's the ultimate distribution of pure strategies?
Many thanks in advance for any help,
