Asymptotic formula for the number of ways to write a number as the sum of $k$ triangular num...

Use circle method detect the condition $N=\sum_{i=1}^k \frac{m_i(m_i+1)}{2}$ to derive $r(N)=\int_0^1 f^k(\alpha) e(-N\alpha)$, where $f(\alpha)=\sum_{n\leq N} e(\alpha \frac{m_i(m_i+1)}{2} )=\int_ …

stationary phase method in analytic number theory

I hope someone can tell me something about the error term in the formula calculating the oscillatory integral like $\int_a^b g(x)e(f(x))d x$. Specially, the exact formula on page 114 of M. Huxley's gr …

On the prime number theorem in arithmetic progression

Siegel - Walfisz theorem states $$\psi(x,q;a)=x/\phi(q)+O(x/\log^Ax)$$when q is small;q is big ,the results is trival . (When is the Siegel-Walfisz theorem non-trivial?) if $q \ll log^Ax$,we have $ …

Does $L(-1+it,f)\ll_f \log^c q(f)t$ hold ture?

Let $f$ be a holomorphic or Maass cusp form for $SL(2,Z)$. Define $L(s,f)=\sum_{n\ge 1}\frac{a_f(n)}{n^s}$, for $\Im s$ sufficiently large. Then $$L(-1+it,f)\ll_f \log^c q(f)t$$ holds, for some conat …
