PROVIDENCE, RI---Recently mathematicians succeeded in resolving one of the most important questions to arise in number theory in this century. The achievement represents a major advance in the field and provides compelling evidence in a far-reaching research program that lies at the heart of modern number theory.

The Shimura-Taniyama-Weil conjecture, as the question is known, was a central ingredient in Andrew Wiles's celebrated proof of Fermat's Last Theorem. Wiles proved a special case of the conjecture, which was sufficient for his proof of Fermat.

The Shimura-Taniyama-Weil conjecture is as mysterious as it is profound, for it links two seemingly unrelated areas of mathematics: elliptic curves and modular forms. For decades mathematicians studied these two areas, uncovering mysterious connections between the two without being able to pin down the exact relationship. Just as astronomers linked the heavens and earth through the discovery that stars are made up of the same elements found here on earth, so the proof of the Shimura-Taniyama-Weil conjecture provides a bridge between two very different mathematical worlds, that of elliptic curves and that of modular forms.

The proof of the conjecture provided mathematicians with plenty of reason to cheer, but there is more. The Shimura-Taniyama-Weil conjecture is part of what is known as the "Langlands Program", a vast mathematical edifice formulated by the mathematician Robert Langlands. As the central paradigm for modern number theory, the Langlands Program provides a bold and sweeping vision uniting whole areas of mathematics. The proof of the Shimura-Taniyama-Weil conjecture, as well as Wiles's work on Fermat's Last Theorem, provide intriguing insights into the Langlands Program and promise to keep number theorists busy well into the new millennium.

"The Shimura-Taniyama-Weil conjecture, and its subsequent, just-completed proof, stand as a crowning achievement of number theory in the twentieth century," writes number theorist Henri Darmon in the article "A Proof of the Full Shimura-Taniyama-Weil Conjecture Is Announced". The article will appear this week as a special Research News item in the December 1999 issue of the Notices of the AMS.

Founded in 1999 to further mathematical research and scholarship, the 30,000-member AMS fulfills its mission through programs and services that promote mathematical research and its uses, strengthen mathematical education, and foster awareness and appreciation of mathematics and its connections to other disciplines and to everyday life.
