Serre's Modularity Conjecture

Definition

Serre's Modularity Conjecture is a significant hypothesis in number theory which proposes that every rational elliptic curve is modular, meaning it can be associated with a modular form. This conjecture connects the realms of algebraic geometry and number theory, suggesting a deep link between the properties of elliptic curves and modular forms, which are essential in understanding solutions to Diophantine equations and properties of L-functions.
