本文研究了具有反射壁的(台球)域D中薛定谔方程本征值Ej(alpha)上的和zeta(s; alpha)等于Ej= 1无穷大(Ej(alpha))-s,其中有一条磁通量α穿过。对于整数s,通过推广Itzykson等人的绿色函数技术(同上,vol.19,L111-5,1986)基于D和单位圆盘之间的保角变换。当变换是由一个多项式的有限次显式公式,使zeta(2; α)可以很容易地计算出高精度。结合半经典近似,zeta(2; alpha)的精确值可以用来计算不可积台球的基态E1(alpha),误差约为1%。
This is a study of the sum zeta (s; alpha ) identical to Ej=1infinity (Ej( alpha ))-s over the eigenvalues Ej( alpha ) of Schrodinger's equation in a (billiard) domain D with reflecting walls, threaded by a single line of magnetic flux alpha . For integer s, zeta (s; alpha ) is calculated by generalising a Green function technique of Itzykson et al. (ibid., vol.19, L111-5, 1986) based on a conformal transformation between D and the unit disc. When the transformation is generated by a polynomial of finite degree an explicit formula enables zeta (2; alpha ) to be easily computed with high accuracy. In conjunction with a semiclassical approximation the exact values of zeta (2; alpha ) can be used to calculate the ground state E1( alpha ) for a non-integrable billiard, with an error of about one per cent.
