Abstract

The existence of semi-pullbacks for stochastic relations over analytic spaces is addressed. It is shown by means of a measure extension that the theory of measurable selectors for measurable relations may be employed for its solution. The category of stochastic relations is shown not to have (weak) pullbacks.
