This question was migrated from MSE when it is not a statistic question, but instead about the mathematical compatibility between two frameworks: Geometric Brownian Motion model through SDEs series and the efficient frontier analysis by Markowitz portfolio theory. I am looking for a mathematical demonstration. I hope you reconsider to migrate it back. Thanks beforehand.

Q: If known, would the the numbered Riemann Zeta zero that could theoretically have value other than 1/2 be useful AND functionally important?

Zac U.I get that it would disprove RH. Say for instance the number has 800 trillion decimal digits so maybe not now but sometime perhaps in near future computers could work with. How would this be accomplished? Is there a way to work with the n-th? Are there concrete ideas on what it might lead to?

Do you think Solving an exponential and logarithmic equation with Lambert W function ($a^x=\log_a(x)$) is a duplicate of Solutions of $a^{a^x}=x$ for fixed $a>0$?The equations can easily be put in terms of one another.

Q: Prove or disprove: $\forall a \ne k^2, \exists b, a^3 - b^2 \in \mathbb{P}$

PinkRabbitIn a forum post the following conjecture was proposed with no background information. For all positive non-square number $a$, there exists integer $b$ such that $$ a^3 - b^2 \text{ is a prime number.} $$ E.g., $6^3 - 5^2 = 191$, $8^3 - 3^2 = 503$, and $14^3 - 5^2 = 2719$ are all primes. I have ...

C off-topic SV, missing doubt context, and trivial, and surely a dupe too.
