comment How can a set be a subset of a $\sigma$-algebra
Just to clarify, if I wrote $S\subset 2^X$, it would be fine, right?

Sorry for editing the question like that, I originally misunderstood what the person that brought this to my attention said and posed a completely wrong question.

comment Why does $\sigma (X_t) \subset \sigma (X)$ hold?
