Based on the viewpoint of duality, this paper studies the interaction between a curved surface body and an inside particle. By convex/concave bodies with geometric duality, interaction potentials of particles located outside and inside the curved surface bodies are shown to have duality. With duality, the curvature-based potential between a curved surface body and an inside particle is derived. Furthermore, the normal and tangential driving forces exerted on the particle are studied and expressed as a function of curvatures and curvature gradients. Numerical experiments are designed to test accuracy of the curvature-based potential. 展开更多

In 2005, the classical intersection bodies and L_p intersection bodies were extended. Afterwards, the concept of gen-eral L_p intersection bodies and the generalized intersection bodies was introduced. In this paper, we define the generalized bodies with parameter. Besides, we establish the extremal values for volume, Brunn-Minkowski type inequality for radial combination and L_p harmonic Blaschke combination of this notion. 展开更多

If L is a star body in Rn whose central(n-i)-slices have the same(n-i)-dimensional measure μn-1(with appropriate density) as the central(n-i)-slices of an origin-symmetric star body K, then the corresponding ... If L is a star body in Rn whose central(n-i)-slices have the same(n-i)-dimensional measure μn-1(with appropriate density) as the central(n-i)-slices of an origin-symmetric star body K, then the corresponding n-dimensional measures μn of K and L satisfy μn(K)≤μn(L). This extends a generalized Funk's section theorem for volumes to that for measures. 展开更多

The Funk's section theorem in the n-complex space Cn is investigated. It turns out that this theorem does not admit an extension for the class of general origin-symmetric star bodies in Cn but for a class of star bodies called generalized complex intersection bodies. A quasi-version of Funk's section theorem in Cn is established then. 展开更多
