Special geodesics and atypical intersections

Matteo Tamiozzo

Let $C$ be a complex irreducible plane curve that is not the vanishing locus of a modular polynomial. We show that $C$ contains finitely many real algebraic curves whose projection…

Special curves in modular surfaces

Matteo Tamiozzo

We show that geodesics in the upper half-plane attached to a maximal split torus or a real quadratic torus in $G L_{2, Q}$ are the only irreducible algebraic curves whose i…

The tame Hilbert symbol via K-theory and central extensions

Matteo Tamiozzo

Let $K$ be a mixed characteristic local field whose residue field has cardinality $q$ , and let $n$ be an integer dividing $q - 1$ . In the first part of this document we construct a $…
