Elliptic surfaces

Definition

Elliptic surfaces are algebraic surfaces that contain a fibration structure over a base curve where the fibers are elliptic curves. This concept is significant as it bridges the study of algebraic geometry and number theory, particularly in understanding the properties and applications of elliptic curves in various mathematical contexts, including the Taniyama-Shimura conjecture.
