考虑Rn中凸体K的i-曲率函数fi(K,·)和Lp-曲率函数fp(K,·)的积分扩张,引入了i-混合曲率函数fp,i(K,·)的概念,并讨论了Lp-混合质心体算子的Busemann-Petty类似问题,即Γ-p,iK <$Γ-p,iL是否蕴涵Wi(K)≤Wi(L),得到了一些推广的结果.
An integrated extension of the i-curvature function fi(K,·) and the Lp-curvature function fp(K,·) for a convex body K in Rn is considered.The concepts of the i-mixed curvature function fp,i(K,·) is introduced.Then the analog question of the Busemann-Petty for the operator of Lp-mixed centroid bodies,that is,whether Γ-p,iKΓ-p,iL implies Wi(K)≤Wi(L),is considered.Some generalized results are obtained.
