根据任意n个P的单位外法向量张成的空间的维数,将R n中多边形P的体积泛函V n的n次幂分解为n次齐次多项式。建立了R 3中这些体积分解泛函的一组新的尖锐仿射等周不等式,从本质上表征了R n中多边形的几何和代数结构。
The nth power of the volume functional V n of polytopes P in R n, according to dimensions of the spaces spanned by any n unit outer normal vectors of P, is decomposed into n homogeneous polynomials of degree n. A set of new sharp affine isoperimetric inequalities for these volume decomposition functionals in R 3 are established, which essentially characterize the geometric and algebraic structures of polytopes.
