SIAM Journal on Numerical Analysis, Vol. 20, No. 5 (Oct., 1983), pp. 1023-1031 (9 pages) In this paper a scheme is presented to numerically evaluate the argument principle for a real polynomial on the ...

The goal of this paper is to obtain some comparison inequalities for a linear operator between polynomials in the plane. The polynomials under study have constraints on their zeros and the estimates ...
