A Note on Visser’s Inequality
摘要
Abstract
Certain new estimates for the coefficients of a polynomial are obtained, which among other things furnishes new but equivalent forms of some well known results of V.K. Jain [Bull. Math. Soc. Math. Roumanie Tome 49 (97), no. 2, 171–175 (2006)] and S. Gulzar [C. R. Acad. Sci. Paris, Ser. I 354, 357–363 (2016)].
