将经典的对偶混合体积概念推广到Lp空间,提出了“q-全对偶混合体积”的概念.将传统的p≥1的Lp投影体概念拓展,提出p〈1时的Lp投影体和混合投影体概念,并且建立了Lp-极投影Brunn—Minkowski不等式.作为应用,推广了熟知的极投影Brunn—Minkowski不等式,获得了投影Brunn—Minkowski不等式的Lp空间的极形式.
In this paper, the authors first generalize the notion of classical dual mixed volume to Lp-space and introduce the notion of q-dual mixed volume. Moreover, they extend the notion of classical Lp(p ≥ 1)-projection bodies and introduce the notions of Lp(p 〈 1)-projection and mixed projection bodies, and establish the Brunn-Minkowski inequality for Lp-polar mixed projection bodies. As applications, the well-known Brunn- Minkowski inequality for polar of projection bodies is generalized and an Lp-polar form of Brunn-Minkowski inequality for projection bodies is obtained.
