Reducing Models for Branched Covers of the Projective Line

Explore methods for computing small affine plane models of curves over number fields that map to the projective line in this 31-minute mathematical lecture. Learn techniques for taking a curve equipped with a finite degree map to the projective line and reducing it to a minimal (possibly singular) affine plane model. Discover computational approaches that minimize the complexity of these geometric objects while preserving their essential mathematical properties. Gain insights into the intersection of algebraic geometry, number theory, and computational mathematics through practical methods for model reduction. Understand how these techniques apply to branched covers and their geometric representations, with applications in arithmetic geometry and related fields.
