Abstract:
We demonstrate continuous operators on function spaces from a probability space to a simplex such that the only fixed points of these operators is a function that cannot be measurable with respect to any finitely additive measure that extends the probability measure. We believe this situation is ubiquitous and exists in many other contexts.
