应用c.Riemannzetafunction的一个基本的积分表示其核心就是Gamma函数。而许多zeta函数的推广都离不开Gamma函数。 应用d.Laplace变换和Mellin变换,这两个十分重要的积分变换,可以十分好的统一在Gamma函数的积分表示上。也就是说,Gamma函数是指数函数的Mellin变换,同时还是幂函数的Laplace变换。
The beta function is defined by B(z,w)=∫10tz−1(1−t)w−1dt=Γ(z)Γ(w)Γ(z+w). TheΓ(z)term is the gamma function Γ(z)=∫∞0tz−1e−tdt. References [1] Olver, F. W. J., A. B. Olde Daalhuis, D. W. Lozier, B. I. Schneider, R. F. Boisvert, C. ...
