关于边长极小的三角形
On triangles with a minuscule side
摘要:
设$W\subset O(V)$是根系$R\subset V$的Weyl群。如果$a+b+c=0=a'+b'+c'$与$a$、$b$和$c$分别与V中的$a'$、$b'$和$c'$共轭,则当$a$到$V$的不可约分量的每个投影与极小余权共线时,$(a,b,c)$与$V^3$中的$(a',b',c')$共轭。
英文摘要:
Let $W\subset O(V)$ be the Weyl group of a root system $R\subset V$. If $a+b+c=0=a'+b'+c'$ with $a$, $b$ and $c$ respectively conjugated to $a'$, $b'$ and $c'$ in V , then $(a,b,c)$ is conjugated to $(a',b',c')$ in $V^3$ when each projection of $a$ to an irreducible component of $V$ is co-linear to a minuscule coweight.
