利用非阿基米德局部域F上的离散余紧无挠子群PgL3,得到了PgL3的Bruhat-Tits构造商的有限商XΓ的Zeta函数Z(XΓ,u)的闭式表达式.类似于图Zeta函数,Z(XΓ,u)是一个具有两个不同表达式的有理函数,它满足黎曼假设当且仅当XΓ是Γ复形.
In this paper we obtain a closed form expression of the zeta function Z (X Γ, u) of a finite quotient X Γ of the Bruhat–Tits building of PGL 3 over a nonarchimedean local field F by a discrete cocompact torsion-free subgroup Γ of PGL 3. Analogous to a graph zeta function, Z (X Γ, u) is a rational function with two different expressions and it satisfies the Riemann hypothesis if and only if X Γ is a Ramanujan complex.
