Abstract

Abstract: Two sharp Chernoff type inequalities are derived for star bodies in $\mathbb{R}^2$ , one is an extension of the dual Chernoff-Ou-Pan inequality, and the other is the reverse Chernoff type inequality. Furthermore, we establish a generalized dual symmetric mixed Chernoff inequality for two planar star bodies. As a direct consequence, a new proof of the dual symmetric mixed isoperimetric inequality is presented.

Key words: Chernoff type inequality, Fourier series, $k$ -order radial function, reverse Chernoff type inequality
