Clay Mathematics Institute

Dedicated to increasing and disseminating mathematical knowledge

The Clay Mathematics Institute: Overview and History

CMI Opening Event

The Clay Mathematics Institute (CMI) was incorporated in 1998 by Mr Landon T. Clay. Its establishment grew out Landon Clay's belief in the value of mathematical knowledge and its centrality to human progress, culture, and intellectual life.

Landon Clay, a graduate of Harvard College, has had a distinguished career as a successful businessman and in finance and science-based venture capital funding. He has also devoted a great deal of thought and energy to philanthropic causes, from archaelogy and astronomy to biology and mathematics. He believes that science and mathematics have made enormous contributions to mankind's welfare and understanding of the world, and that the role of mathematics will grow ever more important in the future.

The primary objective of CMI is to encourage the increase and dissemination of mathematical knowledge.

Principal Activities

CMI may be best known for the seven Millennium Prize Problems announced at the Collège de France in Paris in June of 2000. The prizes were established by CMI to (i) recognize some of the arguably most difficult problems with which mathematicians were struggling at the turn of the millennium, (ii) to underline the importance of working on the really hard problems, and (iii) to spread the news that in mathematics hard, significant problems still abound - the frontiers of knowledge are still wide open.

The Millennium Prize Problems constitute but one of CMI's activities. Two of the largest, in terms of both budget and importance, are the Clay Research Fellowships and the Clay Research Conference and Workshops, the latter being the venue at which the Clay Research Awards are presented.

One or more Clay Research Fellows are selected each year by CMI's scientific advisory board for a term of two to five years. Fellows are generously supported on a twelve month basis, and may carry out their work at any institution or combination of their choice. Fellows are not restricted by nationality or country of residence.

Research Summer School

The Clay Research Summer Schools bring approximately one hundred advanced graduate students and recent PhD's together with an outstanding faculty for one month of intensive study of an area of current active research interest. The aim of the school is to give its participants the intellectual tools and capital and the intuitive "feel" for the subject, that they they need to make future research contributions of a high order. The lectures of the schools are published by CMI in its proceedings series. Six months after print publication, they become available on the CMI website. The schools are each held at a different host institution.

CMI also runs week-long 'research schools' in partnership with the London Mathematical Society.

Rapid Response

Because of its status as a private foundation, CMI is able to react quickly to events and has great flexibility in supporting new research developments. Most notable in this regard was its support of Bruce Kleiner and John Lott as Clay Research Scholars for part of the time that they were writing their Notes on Grigori Perelman's work on the Poincaré and Thurston (Geometrization) conjectures; the organization by John Lott Gang Tian of a workshop on Perelman's work at Princeton in 2004; and the support of John Morgan and Gang Tian of a monograph on Perelman's work.


In addition to special workshops such as that on Perelman's work, which are organized off-site, CMI also conducted a regular series of workshops at its Bow Street office in Cambridge, MA. These are now held in the UK at Oxford. Generally small in size and short in lead time, these workshops give researchers the opportunity to come together and share ideas in an informal setting. There is no set format; it is determined by the workshop organizer's needs and preferences.

Enhancement and Partnership

CMI also has a scheme to run events in partnership with other organisations or to enhance activities that are already planned, particularly by funding international participation.

Special Projects

Again because of its status as a private foundation with a very general charter, CMI from time to time undertakes special projects to disseminate mathematics. Notable are its digitization and film projects. In 2005, CMI, in collaboration with and the Bodleian Library at Oxford University, produced a digital copy of the oldest extant copy of Euclid's Elements, dating from 888 AD, when it was copied in Constantinople from a earlier manuscript. The original, written in Alexandria around 350 BC, is of course long lost. An edition of the digital copy, featuring a proposition-by-proposition index, is available in the historical section of the online library. Other digitization projects include (a) the manuscript of Riemann's 1859 paper on the distribution of prime numbers in which the Riemann hypothesis is stated, (b) the complete Klein Protokolle - Felix Klein's seminar in Goettingen from 1872 to 1912 - forty years of mathematics!
