Algebraic Properties of the Ideal of Spectral Invariants for the Discrete Laplacian

Matthew Faust, Leo Friedman, Gavin O'Malley +2

Let $\Gamma =q_1\mathbb{Z}\oplus q_2\mathbb{Z}\oplus \cdots \oplus q_d\mathbb{Z}$, with $q_j\in {\mathbb{Z}}^{+}$ for each $j\in \{1,\dots ,d\}$, and denote by $\Delta$ the discrete Laplacian on $…
