Inequalities Involving the Derivative of Rational Functions With Prescribed Poles
This paper gives an upper bound of a modulus of the derivative of rational functions. rz=z−z0shz/wz∈Rm,n, where rz has exactly n poles a1,a2,⋯,an and all the zeros of rz lie in Dk∪Dk+,k≥1 except the zeros of order s at z0,z0<k. Moreover, we give an upper bound of a modulus of the derivative of ra...
