A degenerate version of Brion's formula

Carsten Peterson

Let $p \subset V$ be a polytope and $I^¾ \in V_{C}^{*}$ . We obtain an expression for $I (p; I^\pm) := \int_{p} e^{⟨ I^\pm, x ⟩} d x$ as a…

The discrete wave equation with applications to scattering theory and quantum chaos

Carsten Peterson

With a view towards studying the multitemporal wave equation on affine buildings recently introduced by Anker-RÃ©my-Trojan [arXiv:2312.06860], we systematically develop the basic p…
