证明了当n ≥ 5时,SL(n; Z)的Dehn函数是二次函数.这个证明涉及到将SL(n; R)/SO(n)中的圆盘分解成不同大小的三角形。通过将这些三角形映射到SL(n; Z)中,并用“捷径”代替大型初等矩阵,我们得到了特定形式的单词,并使用组合技术来填充这些循环。
We prove that when n >= 5, the Dehn function of SL(n; Z) is quadratic. The proof involves decomposing a disc in SL(n; R)/SO(n) into triangles of varying sizes. By mapping these triangles into SL(n; Z) and replacing large elementary matrices by "shortcuts," we obtain words of a particular form, and we use combinatorial techniques to fill these loops.
