报告摘要:
We study the distribution of integral matrices with a fixed characteristic polynomial. We determine the leading term of the distribution in terms of zeta functions of orders. The proof is based on an equi-distribution property of orbits, a reformulation of the distribution into orbital integrals via the strong approximation with Brauer-Manin obstruction and the Tate-Nakayama duality, endoscopic fundamental lemma, and a critical input that links orbital integrals to residues of zeta functions of orders. This is a joint work with Taiwang Deng.
