A Jacobian variety is an algebraic structure that parametrizes line bundles on a curve, playing a crucial role in algebraic geometry. It is associated with an algebraic curve and serves as an abelian variety, providing insights into the relationships between the curve and its points. These varieties have deep connections to several fundamental concepts in number theory and algebraic geometry, particularly in the context of divisors and their associated linear systems.
