摘要
设a>1,R_G=R_G(a)表示Grotzsch环,它的余集分支由单位球|x|≤1和射线a≤x_1<∞,x_2=x_3=…x_m=0组成,它的模modR_G(a)记为logΦ(a),本文证明了关于模函数Φ(a)的若干不等式.
Suppose that a>1 we let R_G=R_G(a) be the Grotzsch ring whose complementary components consist of the ball |x|≤1 and the ray a≤x_1<∞, x_2=x_3=...=x_n =0, We denote its modlus by mod R_G(a)=logΦ(a),In this paper,we have proved several inequalities for the modular function Φ(a).
