摘要:

Petty投影不等式和Busemann-Petty质心不等式是经典Brunn-Minkowshi理论的基本不等式.在最近的研究中,Lutwak,Yang,Zhang又把以上2个不等式推广到Lp Brunn-Minkowshi情形中.该文的目的是建立起Lp-Petty投影不等式和Lp Busemann-Petty质心不等式的等价性.

关键词: Lp投影不等式;Lp质心不等式; 等价性

Abstract:

Petty’s projection inequality and Busemann-Petty centroid inequality are the basic inequalities in the classical Brunn-Minkowshi theory. In the recent studies, Lutwak, Yang and Zhang generalized the above two inequalities into the circumstances of Lp  Brunn-Minkowshi. The purpose of the present paper is to show equivalence of the Lp  Petty projection inequality and the Lp Busemann-Petty centroid inequality.

Key words: Lp projection inequality; Lp centroid inquality; equivalence
