Petty猜想断言,在所有凸体中,商式\\(V_n(\Pi K)/V_n(K)^{n-1}\\)恰好由椭球体取得最小值。本文证明了在\\(\mathbb R^n\\)(\\(n\geq3\\))中所有旋转凸体均满足该猜想,并包含了等号成立的情形。
英文摘要
The Petty conjecture asserts that the quotient \(V_n(ΠK)/V_n(K)^{n-1}\) is minimized among all convex bodies precisely by ellipsoids. In this paper, we prove the conjecture for all convex bodies of revolution in \(\mathbb R^n\), \(n\geq3\), including the equality cases.
