Analytic number theory

Use complex analysis, multiplicative structure, and harmonic methods to study primes and arithmetic averages.

  1. 01

    Arithmetic functions and Dirichlet convolution

    Organize divisor identities with convolution, multiplicativity, and Möbius inversion.

    24 min
  2. 02

    Partial summation and Abelian estimates

    Transfer cancellation in partial sums into estimates for weighted arithmetic sums.

    25 min
  3. 03

    Dirichlet series and Euler products

    Translate divisor convolution into analytic products inside a justified half-plane.

    26 min
  4. 04

    Riemann zeta function and analytic continuation

    Continue zeta beyond its defining series while keeping poles, gamma factors, and special values distinct.

    28 min
  5. 05

    Zeros and explicit formulas

    Relate prime-power counts to zeta zeros with precise endpoint and truncation conventions.

    31 min
  6. 06

    Dirichlet characters and L-functions

    Encode multiplicative residue classes while distinguishing a character’s modulus from its conductor.

    29 min
  7. 07

    Primes in arithmetic progressions

    Use character orthogonality to separate eligible residue classes and scope their prime-counting asymptotics.

    28 min
  8. 08

    Perron formula and contour shifting

    Invert a Dirichlet series with endpoint weights and keep every contour error under control.

    32 min
  9. 09

    Sieve methods and Brun–Titchmarsh

    Count survivors of divisibility filters and apply a uniform upper bound with its correct range.

    30 min
  10. 10

    Exponential sums and Weyl differencing

    Reduce polynomial oscillations by differencing and state cancellation bounds with a leading-coefficient approximation.
