"Maass forms"의 두 판 사이의 차이

2010년 3월 5일 (금) 19:05 판

z = x + iy in the upper half-plane
Re(s) > 1
definition
\(E(z,s) ={1\over 2}\sum_{(m,n)=1}{y^s\over|mz+n|^{2s}}\)
Maass form
\(\DeltaE(z,s)=-y^2\left(\frac{\partial^2}{\partial x^2}+\frac{\partial^2}{\partial y^2}\right)E(z,s) = s(1-s)E(z,s)\)
functional equation
\(E^{*}(z,s) = \pi^{-s}\Gamma(s)\zeta(2s)E(z,s) \)
\(E^{*}(z,s)=E^{*}(z,1-s)\)
a unique pole of residue 3/π at s = 1

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
\(K(a,b;m)=\sum_{0\leq x\leq m-1,\ gcd(x,m)=1 } e^{2\pi i (ax+bx^*)/m}\)
