An undergraduate math student deeply interested in number theory. I learn by asking and answering tough questions on this community.

Have a glance of my field of interest in these answers:

Simple proof for a general Brun's upper bound sieve

Asymptotic formula for Mean of Sum of Power of Divisors $\frac{ \sum_{i=1}^{n}\sigma_v(i)}{n}\sim\frac{n^v\zeta(v+1)}{v+1}$

Jensen's Formula and the number of zeros.

Proof: If convergence of Dirichlet series in one point, then uniform convergent in a sector

Volume of a $l_2$ ball of radius $r$

Prove that $\sum_{n\leq x , gcd(3,n)=1} \frac{ \tau(n)}{n} = \frac{ 2(\log x)^2} {9} +O(\log x)$
