Taniyama-Shimura Conjecture

Definition

The Taniyama-Shimura Conjecture posits a deep relationship between elliptic curves and modular forms, asserting that every elliptic curve over the rational numbers is associated with a modular form of weight 2. This conjecture, which originated in the mid-20th century, became a pivotal point in number theory, linking these two seemingly different areas and leading to significant advancements in our understanding of both elliptic curves and modular forms.
