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
