Joe Peter Buhler (born 1950 in Vancouver, Washington) is an American mathematician known for his contributions to algebraic number theory, algebra and cryptography.

Education and career[edit]

Buhler received his undergraduate degree from Reed College in 1972, and his Ph.D. from Harvard University in 1977 with thesis Icosahedral Galois Representations and thesis advisor John Tate.[1][2] Buhler was a professor at Reed College in Portland, Oregon from 1980 until his retirement in 2005.[3] From 2004 to 2017, he was director of the IDA Center for Communications Research in La Jolla, California.[4]

In 1997, he introduced, with Zinovy Reichstein, the concept of essential dimension.[5]

Buhler is involved in a project to numerically verify the Kummer–Vandiver conjecture of Harry Vandiver and Ernst Eduard Kummer concerning the class number of cyclotomic fields. Vandiver proved it with a desk calculator up to class number 600, Derrick Lehmer (in the late 1940s) to about 5000, and Buhler with colleagues (in 2001) to 12 million.[6] He continues the project with David Harvey and others.[7]

He was elected a Fellow of the American Mathematical Society in 2012.
