A quotient of the Bruhat-Tits building classifying maximal matrix orders over curves
Luis Arenas-Carmona, Claudio Bravo, Ignacio Saavedra
In a previous work, we defined a quotient graph of the Bruhat-Tits tree associated to the degree two special linear group over a local field whose vertex set is in correspondence w…

On some branches of the Bruhat-Tits tree
Luis Arenas-Carmona, Ignacio Saavedra
We give an algorithm to explicitly compute the largest subtree, in the local Bruhat-Tits tree for PSL_2(k), whose vertices correspond to orders containing a given suborder H, in te…
