论文摘要
我们为$ a_ {n-1}，b_n $和$ d_n $的Weyl室的圆锥固有卷的公式提供了新的直接证明。这些公式根据第一类及其$ b $ - 和$ d $ -Analogues的Stirling数字表示圆锥固有的量。证明涉及明确确定Weyl腔室面部的内部和外部角度。
We give a new, direct proof of the formulas for the conic intrinsic volumes of the Weyl chambers of types $A_{n-1}, B_n$ and $D_n$. These formulas express the conic intrinsic volumes in terms of the Stirling numbers of the first kind and their $B$- and $D$-analogues. The proof involves an explicit determination of the internal and external angles of the faces of the Weyl chambers.
