Some new inequalities for gamma and polygamma functions

2005
The author proves new inequalities concerning the gamma function \(\Gamma\), \[ \Gamma(x)=\int_0^\infty e^{-u} u^{x-1} du, \] polygamma functions \(\psi=\Gamma'/\Gamma\) and \(\psi'\). These functions have applications in mathematical physics and statistics.
