Q: Girsanov's theorem for Gaussian measures as the Cameron-martin theorem with a random shift

Robert WegnerLet $H \subset E$ be the Cameron-Martin space of a Gaussian measure $\mu$ on a separable Banach space $E$. The Cameron-Martin theorem states that for all $h \in E$ we have $h \in H$ if and only if $\mu(\cdot + h)$ is equivalent to $\mu$, and then the Radon-Nikodym derivative is $$ \frac{d\mu(\cdo...

Q: Asymptotic behavior of partial sums of Dirichlet series

 BabarConsider the Dirichlet series: $$\sum_{n \geq 1} \frac{a_n}{n^s} = \frac{\zeta(s+1/3)}{\zeta(s)}$$ where $\zeta(s)$ is the Riemann zeta function. Question: Assuming the Riemann Hypothesis (RH), how can we prove that: $$\sum_{n \leq x} a_n \sim \frac{x^{2/3}}{(2/3)\zeta(2/3)} \quad \text{as } x \t...

I figure we can reserve NULLs for "not filled". Then...
