I have a question about cofactors: Could the following be true?
If a dynamical system is compact, metric and the map T is continous, is every
function f in L(2) (or L(p) for p bigger than 1) cohomolgous to a
continous function?
My own training is in probability theory, and my reading in the relevant
literature seems to suggest the the result above is a "folk theorem" Can any on
e provide me with a reference? Is the result known in special cases, like
irrational rotations?
