Zeta Functions of Finite Graphs and Representations of $p$-Adic Groups
TL;DR: In this paper, a generalization of the definition of zeta function is presented, and the computation of Zx(u) for some well known families of graphs is discussed.
Journal ArticleDOI
Shimura curves as intersections of Humbert surfaces and defining equations of {QM}-curves of genus two
Journal ArticleDOI
On Brumer's family of {RM}-curves of genus two
TL;DR: In this paper, the authors reconstruct Brumer's family with 3-parameters of curves of genus two whose jacobian varieties admit a real multiplication of discriminant 5, which can be described in three distinct ways, i.e., by Humbert's modular equation, by Poncelet's pentagon and by algebraic correspondences.
