论文摘要
在Mergelyan类型近似中,我们通过多项式函数或有理函数或有理形态函数在包含K的不同开放集上均匀地近似函数K。在本文中,我们考虑的类似近似值,其中k上的均匀收敛被所有顺序衍生物的k均匀近似所代替。
In Mergelyan type approximation we uniformly approximate functions on compact sets K by polynomials or rational functions or holomorphic functions on varying open sets containing K. In the present paper we consider analogous approximation, where uniform convergence on K is replaced by uniform approximation on K of all order derivatives.
