      An asymptotic formula for a sum involving powers of floor functions

      Let $\theta \geq 0$ and consider the sum $$\sum_{n \leq x} \left\lfloor \frac{x}{n} \right\rfloor^{-\theta}.$$. I have seen the claim that there is a constant $c(\theta)$ (depending on $\theta$!) ...

      Convergence with the recurrence $T_{n+1}=T_n^2-T_n+\frac{n}{p_n}$

      For each integer $n\geq 1$ I define the recurrence $$T_{n+1}=T_n^2-T_n+\frac{n}{p_n},$$ with $T_1=1$, where $p_k$ denotes the $k-th$ prime. So multiplying by $(-1)^n$ and telecoping gives that for ...

      Is the ratio of a number to the variance of its divisors injective?

      The variance $v_n$ of a natural number $n$ is defined as the variance of its divisors. There are distinct integer whose variances are equal e,g. $v_{691} = v_{817}$. However I observed that for $n \le ...
