Some new types of doubly
stochastic measures are constructed. Using measure preserving transformations, one
can construct examples of nontrivial extreme doubly stochastic measures which are
absolutely continuous with respect to another extreme doubly stochastic measure
(disproving a conjecture by Feldman). By combinatorial arguments, one
gets an extreme doubly stochastic measure that is not concentrated on a
countable union of function graphs and whose support is the whole unit
square.
