An influential publication gathering extended, peer-reviewed research in pure and applied mathematics. Featuring cohesive series of papers under expert guidance from the AMS journal Transactions, it offers a forum to explore profound advances and stimulate inquiry into enduring mathematical challenges.

The Memoirs of the AMS is devoted to the publication of new research in all areas of pure and applied mathematics. The Memoirs is designed particularly to publish long papers of groups of cognate papers in book form, and is under the supervision of the Editorial Committee of the AMS journal Transactions of the American Mathematical Society. All papers are peer-reviewed.
