» Analysis of Dirac Type and Higher Spin Operators Conference: Honoring John Ryan
Conference Information
Chapman University is proud to organize the conference “Analysis of Dirac type and higher spin operators. A conference in honor of John Ryan on the occasion of his retirement” from November 11th to November 13th, 2022.
Professor John Ryan has been a major contributor to Clifford Analysis and to the theory of Dirac operators beginning with his D.Phil. dissertation in 1982, which he completed at the University of York, under the direction of A. Sudbery. John is currently a Distinguished Professor at the Department of Mathematics at the University of Arkansas, Fayetteville, from which he is now retiring after serving successfully for more than 30 years. John has published more than 80 peer reviewed articles, has been the advisor of six doctoral students, and has been the recipient of many grants from a variety of granting agencies; the conference is intended to allow his many collaborators and friends to express their respect and affection for his contributions, while at the same time to provide an opportunity for all of us to exchange our most recent results in areas that have been of great interest to John.
