(Maybe that is the defintion? I don't know this notation.) Then it follows from the definition of "product sigma-algebra" ... if $Y$ is one of the generators of the product sigma-agebra, then your set is well-defined; and the collection of $Y$ such that your set is well-defined is a sigma-algebra. By the way: you also need to define "sub-probability measure". | |
