3rd W.K. Clifford Prize awarded to David Kimsey


The W.K. Clifford Prize is an international scientific prize for young researchers. The prize intends to encourage young researchers to compete for excellence in their research in theoretical and applied Clifford algebras, their analysis and geometry. Moreover, the award should promote solid research and thereby positively raise the profile of the Clifford community in mathematics, physics and the applied sciences.

The W.K. Clifford Prize was instituted in 2011 by the Advisory Board of the International Conference on Clifford Algebras and Their Applications in Mathematical Physics (ICCA), and is awarded each three years at the occasion of an ICCA Conference.

The third laureate Dr. David Kimesey received the W.K. Clifford Prize on 9th of August 2017 at ICCA11 in Gent, Belgium.

Dr. David Kimsey, Lecturer in Pure Mathematics, School of Mathematics and Statistics, Newcastle University (UK), has been selected as the recipient of the third W.K. Clifford Prize, for his outstanding mathematical research achievements in the field of quaternionic analysis with applications in quantum mechanics.

He received his Ph.D. from Drexel University with a thesis titled “Matrix-valued moment problems” (supervisor H. Woerdeman). During two postdocs his interest subsequently moved to quaternionic analysis. Spectral theory for normal operators on a quaternionic Hilbert space is a delicate and technical subject due to the noncommutativity of the quaternions. In particular, the proper notion of spectrum is not immediately obvious. The S-spectrum was only recently introduced and based on this notion, David Kimsey (in collaboration with Alpay and Colombo) produced a completely rigorous analogue of the spectral theorem for bounded and unbounded normal operators on a quaternionic Hilbert space. This spectral theorem is a crucial tool to formulate the axioms of quaternionic quantum mechanics and as such closed a problem formulated by Birkhoff and von Neumann in 1936.

The solution to this longstanding open problem in itself would already warrant awarding the prize to David Kimsey. However, through various collaborations, he also initiated the study of moment problems, free analysis and interpolation in the context of quaternions.

The W.K. Clifford Prize was presented to David Kimsey at the ICCA11 conference at Gent, 07-11 August 2017.
