Webwhich essentially measures how symmetric S is about the point x, and define sym(S):= max x∈S sym(x,S); x∗ is called a symmetry point of S if x∗ achieves the above maximum. The set S is a symmetric set if sym(S) = 1. There are many important properties of symmetric convex sets; herein we explore how these properties extend as a function ... WebApr 11, 2024 · On Beckner's Inequality for Axially Symmetric Functions on. Changfeng Gui, Tuoxin Li, Juncheng Wei, Zikai Ye. We prove that axially symmetric solutions to the -curvature type problem must be constants, provided that . In view of the existence of non-constant solutions obtained by Gui-Hu-Xie \cite {GHW2024} for , this result is sharp.
