摘要
证明了当n≥2,p≥2n- 2,且( - 1)nsgn( C2n- 1) ≥0 时,exp(q) 的p 阶(n ,n) 有理逼近Rnn( q) 的阶星形有n 个齿弧完全含于右半复平面。
When n≥2, p≥2n-2, (-1) n sgn (C 2n-1 ) >0, there being n angle arcwises of the order star of rational approximation to exp(q) are in the right C plane. Other 2 properties for the distribution of angle arcwises were given.
