Abstract

In this article we study two classical potential-theoretic problems in convex geometry. The first problem is an inequality of Brunn-Minkowski type for a nonlinear capacity, Cap A , \operatorname {Cap}_{\mathcal {A}}, where A \mathcal {A} -capacity is associated with a nonlinear elliptic PDE whose structure is modeled on the p p -Laplace equation and whose solutions in an open set are called A \mathcal {A} -harmonic.

In the first part of this article, we prove the Brunn-Minkowski inequality for this capacity: \[ [ Cap A ( λ E 1 + ( 1 λ ) E 2 ) ] 1 ( n p ) λ [ Cap A ( E 1 ) ] 1 ( n p ) + ( 1 λ ) [ Cap A ( E 2 ) ] 1 ( n p ) \left [\operatorname {Cap}_\mathcal {A} ( \lambda E_1 + (1-\lambda ) E_2 )\right ]^{\frac {1}{(n-p)}} \geq \lambda \, \left [\operatorname {Cap}_\mathcal {A} ( E_1 )\right ]^{\frac {1}{(n-p)}} + (1-\lambda ) \left [\operatorname {Cap}_\mathcal {A} (E_2 )\right ]^{\frac {1}{(n-p)}} \] when 1 > p > n , 0 > λ > 1 , 1>p>n, 0 > \lambda > 1, and E 1 , E 2 E_1, E_2 are convex compact sets with positive A \mathcal {A} -capacity. Moreover, if equality holds in the above inequality for some E 1 E_1 and E 2 , E_2, then under certain regularity and structural assumptions on

Brunn—Minkowski不等式与非线性容量的一个Minkowsky问题
本文研究了凸几何中的两个经典势论问题。第一个问题是非线性容量Cap a \算子名的Brunn Minkowski型不等式{Cap}_{\mathcal{A}},其中A\mathcal}-容量与一个非线性椭圆PDE有关,该椭圆PDE的结构以p-p-Laplace方程为模型,其在开集中的解称为A\mathical{A〕-harmonic。在本文的第一部分中,我们证明了这个容量的Brun-Minkowski不等式:\[[Cap A⁡ (λE1+(1−λ)E2)]1(n−p)≥λ[第A章⁡ (E1)]1(n−p)+(1−λ)[第A章⁡ (E2)]1(n−p)\left[\operator name{Cap}_\mathcal{A}(\lambda E_1+(1-\lambda)E_2)\right]^{\frac{1}{(n-p)}}\geq\lambda\,\left[\operatorname{Cap}_\mathcal{A}(E_1)\right]^{\frac{1}{(n-p)}}+(1-\lambda)\left[\operatorname{Cap}_\当1>p>n,0>λ>1,1>p>n,0>\lambda>1和E1,E2 E_1,E_2是具有正A\mathcal{A}-容量的凸紧集。此外,如果在某些E1 E_1和E2,E_2的上述不等式中成立等式,则在
