On the location of the zeros of analytic functions

K. K. Dewan and N. K. Govil

International Journal of Mathematics and Mathematical Sciences, 1990, vol. 13, 1-6

Abstract:

In this paper we obtain regions containing all the zeros of a class of analytic functions whose coefficients are subject to certain conditions. Our results sharpen some of the results known in this direction. Also we give some examples to show that in some cases the regions obtained by our results are considerably sharper than the regions obtained by known results.
