AMS Special Session on Combinatorics and Representation Theory, Spring Western Sectional Meeting — California State University, Fresno
$p$-adic representations are important objects in number theory, and stable lattices serve as a connection between the study of ordinary and modular representations. These stable lattices can be understood as stable vertices in Bruhat-Tits buildings. From this viewpoint, the study of fixed point sets in these buildings can aid research on $p$-adic representations. The simplicial balls, in particular, hold an important role as they possess the most symmetry and fastest growth, and are closely related to the Moy-Prasad filtrations. In this talk, I will introduce some results on simplicial balls.

$p$-adic representations are important objects in number theory, and stable lattices serve as a connection between the study of ordinary and modular representations. These stable lattices can be understood as stable vertices in Bruhat-Tits buildings. From this viewpoint, the study of fixed point sets in these buildings can aid research on $p$-adic representations. The simplicial distance holds an important role as it connects the combinatorics of lattices and the geometry of root systems. In particularly, the fixed-point sets of Moy-Prasad subgroups are precisely the simplicial balls. In this talk, I’ll explain those findings and compute their simplicial volume under certain conditions.
