AI总结:

本文在高维空间中验证了Bezdek猜想,假设通过固定点的截面具有反射轴,且互补不变子空间平行于固定超平面,证明了在正交和仿射设置中成立。

摘要:

1999年,K. Bezdek提出猜想,认为在$\mathbb R^3$中,所有平面截面都有反射轴的凸体是椭球体和旋转体。本文在任意维度$n\geq 3$中证明了该猜想,仅假设通过固定点的截面具有反射轴,并且互补不变子空间都平行于固定超平面。结果在正交和仿射设置中均成立。

英文摘要:

In 1999, K. Bezdek posed a conjecture stating that among all convex bodies in $\mathbb R^3$, ellipsoids and bodies of revolution are characterized by the fact that all their planar sections have an axis of reflection. We prove Bezdek's conjecture in arbitrary dimension $n\geq 3$, assuming only that sections passing through a fixed point have an axis of reflection, provided that the complementary invariant subspaces are all parallel to a fixed hyperplane. The result is proven in both orthogonal and affine settings.
