Unitary Shimura varieties at ramified primes and arithmetic transfer

Yu Luo, Andreas Mihatsch, Zhiyu Zhang

We consider unitary Shimura varieties at places where the totally real field ramifies over $\mbQ$. Our first result constructs comparison isomorphisms between absolute and relative…

On the Linear AFL: The Non-Basic Case

Qirui Li, Andreas Mihatsch

The linear Arithmetic Fundamental Lemma (AFL) conjecture compares intersection numbers on Lubin--Tate deformation spaces with derivatives of orbital integrals. It has been introduc…

-Forms on Lubin--Tate Space

Andreas Mihatsch

We extend Gubler--Künnemann's theory of -forms from algebraic varieties to good Berkovich spaces. This is based on the observation that skeletons in such spaces satisfy a tropic…

On Tropical Intersection Theory

Andreas Mihatsch

We develop a tropical intersection formalism of forms and currents that extends classical tropical intersection theory in two ways. First, it allows to work with arbitrary polytope…

Local Constancy of Intersection Numbers

Andreas Mihatsch

We prove that, in certain situations, intersection numbers on formal schemes that come in profinite families vary locally constantly in the parameter. To this end, we define the pr…

Relative unitary RZ-spaces and the Arithmetic Fundamental Lemma

Andreas Mihatsch

We verify new cases of the Arithmetic Fundamental Lemma (AFL) of Wei Zhang. This relies on a recursive algorithm which allows, under certain conditions, to reduce the AFL identity…

On the Arithmetic Fundamental Lemma through Lie algebras

Andreas Mihatsch

We prove that the Arithmetic Fundamental Lemma conjecture of Wei Zhang is equivalent to a similar conjecture, but for Lie algebras, in the case of non-degenerate intersection. We u…
