introduction
- Hyperbolic distribution problems and half-integral weight Maass forms
- Automorphic forms correspond to representations that occur in L2(G/Γ). In the case when G is SL2, holomorphic modular forms correspond to (highest weight vectors of) discrete series representations of G, while Maass wave forms correspond to (spherical vectors of) continuous series representations of G.
Eisenstein series
Kloosterman sum
- used to estimate the Fourier coefficients of modular forms
- definition for prime p
\(S(a,b;p)=\sum_{1\leq x\leq p-1}{\exp(2i\pi (ax+b\bar{x})/p)},\quad\text{where}\quad x\bar{x}\equiv 1\text{ mod } p\) - generally defined as
\(K(a,b;m)=\sum_{0\leq x\leq m-1,\ gcd(x,m)=1 } e^{2\pi i (ax+bx^*)/m}\) - http://blogs.ethz.ch/kowalski/2010/02/26/the-fourth-moment-of-kloosterman-sums/
