特殊酉群的Hadwiger型定理

A Hadwiger-type theorem for the special unitary group

Andreas Bernig

摘要:

计算了SU(n)空间的维数和$\mathbb{C}^n, n \geq 2$上平移不变连续赋值.对于偶数$n$,该维度等于$(n^2+3n+10)/2$ ;对于奇数$n$,该维度等于$(n^2+3n+6)/2$。构造了该空间的一个显式几何基。作为推论,得到了SU(n)的运动学公式.

英文摘要:

The dimension of the space of SU(n) and translation invariant continuous valuations on $\mathbb{C}^n, n \geq 2$ is computed. For even $n$, this dimension equals $(n^2+3n+10)/2$; for odd $n$ it equals $(n^2+3n+6)/2$. An explicit geometric basis of this space is constructed. The kinematic formulas for SU(n) are obtained as corollaries.
