RESULTS FOR ZEROS OF POLYNOMIAL AND ANALYTIC FUNCTION By Roshan Lal Department of Mathematics V.S.K.C. Government Postgraduate College Dakpathar Dehradun-248125 Uttarakhand India Email:rlkeshtwal@gmail.com (Received : August 02, 2019 ; Revised: September 21, 2019) Abstract Let p(z) be a polynomial of degree n. In this paper, we have obtained ring shaped regions containing zeros of complex valued polynomial as well as analytic functions in terms of coefficient of function. Our results improve upon the results earlier proved. 2010 Mathematics Subject Classification: 30C10, 30C15. Keywords and phrases: Polynomials, analytic function, zeros, region |
