 Apr2 comment how to solve this limit Hint: Try factoring out the $\sqrt{x}$ and use limit arithmetic Apr1 comment Markov chains: Condtitional independence implies independence? Edited, hopefully making the question clearer Apr1 revised Markov chains: Condtitional independence implies independence? improved the question, hopefully Apr1 comment History and early development of Mathematics Some help may also be found in these series of lectures (highly recommended, by the way!) youtube.com/playlist?list=PL34B589BE3014EAEB Mar31 comment Markov chains: Condtitional independence implies independence? Not sure what you mean, but $T_i=\tau_j(i)-\tau_j(i-1)$ where $\tau_j(i)$ is the time of i-th return to the state $j$ Mar31 revised Markov chains: Condtitional independence implies independence? added details Mar31 asked Markov chains: Condtitional independence implies independence? Mar31 comment Eigenvalues of nilpotent matrices I will have to read a bit more on $\mathbb R^0$! Thanks. Mar31 accepted Eigenvalues of nilpotent matrices Mar30 comment Eigenvalues of nilpotent matrices Point 2 is false for $k=0$? I didn't even know there could be $k=0$! What is a $0\times 0$ matrix? Also, what do you mean by "anything implies 1"? Mar28 comment Eigenvalues of nilpotent matrices @Batman and the implication $\Leftarrow$ is in these two claims, too? I don't see that. Mar28 comment Eigenvalues of nilpotent matrices and sorry for perhaps a bit nitpicky stream of claims to validate, but I just wanted to make sure my understanding is 100% correct Mar28 comment Eigenvalues of nilpotent matrices added the obligatory question, to make things clear Mar28 revised Eigenvalues of nilpotent matrices added 29 characters in body Mar28 asked Eigenvalues of nilpotent matrices Mar27 accepted How can a set be a subset of a $\sigma$-algebra Mar27 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? Mar27 comment How can a set be a subset of a $\sigma$-algebra Good. Everything alright with the world and the impostor syndrome is quiet again. Thanks!
