Peter A. Clarkson (b. 1957 in Westow, U.K.) is Professor of Mathematics in the School of Mathematics, Statistics, and Actuarial Science at the University of Kent, Canterbury, U.K. He is a member of the editorial boards of nine international journals and has served as Chair, Vice-Chair, and Secretary of the SIAM Activity Group on Orthogonal Polynomials and Special Functions.
Clarkson has published numerous papers on integrable systems (primarily Painlevé equations), special functions, and symmetry methods for differential equations. Together with M. D. Kruskal, he developed the “direct method” for determining symmetry solutions of partial differential equations (J. Math. Phys., 30 (1989) 2201–2213). His well-known book Solitons, Nonlinear Evolution Equations and Inverse Scattering (with M. J. Ablowitz) was published by Cambridge University Press in 1991. He is also coauthor (with J. A. Tuszynski and J. M. Dixon) of From Nonlinearity to Coherence: Universal Features of Nonlinear Behaviour in Many-Body Physics, published by Oxford University Press in 1997.
Clarkson was elected a Fellow of the U.K. Institute of Physics in 1999, and of the U.K. Institute of Mathematics and its Applications in 2010.
Clarkson is author of the following DLMF chapter
