comment Convergence in probability and almost surely when $X_n=n\mathbb{1}_{(n,n+1]}(X)$
Exactly. So $X_n\to0$ almost surely, and this implies convergence in probability. Or one can check that $P(X_n\ne0)=P(n\lt X\leqslant n+1)\to0$, which implies convergence in probability.

comment Convergence in probability and almost surely when $X_n=n\mathbb{1}_{(n,n+1]}(X)$
For every $\omega$, the sequence $(X_n(\omega))$ does converge, but not necessarily to $X(\omega)$. Can you identify this pointwise limit?

comment Lower bound functional binomial r.v.
This might lead eventually to a constant $C$ valid for every $N\leqslant30$, but not for every $N$.

comment two brownian motions in $ \mathbb{Z}^2 $
The definition is already in the post and states unambiguously that the motions in the x and y direction are not independent.

comment Does $v(x)$ suffice to show $f \in BV[a,b]$?
Thus, increasing alone does not suffice. (Do not hesitate to expand on your question. At present, what you are asking exactly is not very clear.)

comment Does $v(x)$ suffice to show $f \in BV[a,b]$?
No, not right: one needs to show that both v and v-f are nondecreasing.

73 pages... Can you be any more specific? And maybe, maybe explain why whatever you are reading can be applied to the situation at hand.

Did you look for related questions on the site before asking? // Where is your suggestion coming from?

comment Sum of random variables of strictly stationary series
"I would like to see maybe some conditions for when this is the case" And how are we supposed to know that this is what you would like? Divination, maybe?

comment Show $0 \leq e^{-x} - \left( 1 - \frac{x}{n} \right)^n \leq \frac{x^2e^{-x}}{n}$ by induction
Is induction mandatory? The proof of the LHS inequality, for example, is direct without induction and quite uneasy to fit into one.
