Zeta functions of quadratic lattices of a hyperbolic plane
Daejun Kim, Seok Hyeong Lee, Seungjai Lee
In this paper, we study the Dirichlet series that enumerates proper equivalence classes of full-rank sublattices of a given quadratic lattice in a hyperbolic plane -- that is, a no…

Zeta functions enumerating subforms of quadratic forms
Daejun Kim, Seok Hyeong Lee, Seungjai Lee
In this paper, we introduce and study the Dirichlet series enumerating (proper) equivalence classes of full rank subforms/sublattices of a given quadratic form/lattice, focusing on…
