摘要 本文研究了单位化的Lp-混合截面体的性质.利用积分方法,建立了Lp-混合截面体及其星对偶体的Lp-Busemann-Petty型不等式.进一步,利用星对偶和算子Ip的关系,建立了星对偶体的Lp-混合截面体的Lp-Busemann-Petty型不等式的类似物.这些结果是已有结论的对偶形式. In this paper, we study some properties of the unitized Lp-mixed intersection body of star body. By applying the integral methods, we establish the analog of Lp-Busemann-Petty inequality of Lp-mixed intersection body and its star dual body. Further, using the relationship between star dual and the operator Ip, the analog of Lp-Busemann-Petty intersection inequality of Lp-mixed intersection body of star dual body is established, which are the dual form of the known results.
