Invitation to the 3rd W. K. Clifford Prize Lecture at UCL London
The Department of Mathematics of University College London honours the laureates of the W. K. Clifford Prize, by offering them the opportunity to deliver a special lecture. William Kingdon Clifford worked from 1871 until his untimely death in 1879 as Professor of Applied Mathematics at the University College London, holding the Goldsmid Chair. The W. K. Clifford Prize was instituted by the International Conference on Clifford Algebras and Their Applications in Mathematical Physics (ICCA). The third special lecture will be given by the 2017 Laureate David Kimsey from Newcastle University (UK).
Venue: Department of Mathematics, University College London, 25 Gordon Street, London, Harrie Massey lecture Theatre (ground floor). Directions.
Date: Friday, the 10th of November 2017.
4.00 pm: Opening session
R. McDonald (Head, Dept. of Mathematics, UCL): William K. Clifford and UCL
4.10 pm: 3rd W. K. Clifford Prize Winner Lecture
D. Kimsey: The spectral theorem for a normal operator on a quaternionic Hilbert space based on the S-spectrum
5.00 pm: Reception offered by the Department of Mathematics UCL in room 502 (5th floor).
People who wish to attend the reception are kindly requested to register (until the 1st of November 2017) by sending an email message to Hendrik De Bie, firstname.lastname@example.org, Secretary of the W.K. Clifford Prize Committee.
The Laureate 2017 – ICCA11 Gent
David Kimsey of 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 and turns out to be given by the recently discovered S-spectrum. 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.
