无限双曲Kazhdan群的十六相关子表示

A sixteen-relator presentation of an infinite hyperbolic Kazhdan group

Pierre-Emmanuel Caprace

摘要:

本文给出了一个具有$4$生成元和$16$关系元的无限双曲Kazhdan群的显式表示,该关系元的长度至多为$73$ .该群在$(3,4,4)$类型的双曲三角形建筑物上正确地起作用并协紧。我们还指出了一个变化的建设,产生的例子格在$\tilde A_2$ -建筑物承认非Deserkesian剩余的任意素数的权力秩序。

英文摘要:

We provide an explicit presentation of an infinite hyperbolic Kazhdan group with $4$ generators and $16$ relators of length at most $73$. That group acts properly and cocompactly on a hyperbolic triangle building of type $(3,4,4)$. We also point out a variation of the construction that yields examples of lattices in $\tilde A_2$-buildings admitting non-Desarguesian residues of arbitrary prime power order.
