Comment: Likely meets WP:NPROF but needs either (1) to be written in a neutral tone, or (2) promotional language needs to be sourced to reliable and secondary sources. Bobby Cohn (talk) 23:17, 29 July 2024 (UTC)
Robert T. Sharp (1922–2001) was a mathematical physicist who pioneered the application of group theory in physics.[1] Sharp started the tradition of the use of algebraic and group theoretical methods in mathematical physics.[2] He held positions at the University of Alberta and McGill University and collaborated with Jiří Patera and Pavel Winternitz at the Centre de Recherches Mathématiques (CRM). Until his retirement from McGill, he held a chair as MacDonald Professor of Physics.[3]
Sharp's early work focused on nuclear and elementary particle physics. He published a paper in 1953 on approximate wave functions for unbound relativistic particles in a Coulomb field.[4] He made contributions to group theory by developing a simple method for calculating Clebsch-Gordan coefficients.[5] He and his collaborators and students applied this method to the group SU(3), which plays a crucial role in the classification of hadrons.[1] Sharp solved the missing label problem, which arises when dealing with representations of Lie groups.[6] His innovative approach provided a systematic way to specify quantum numbers in group theoretical calculations.[1] He also worked on applications of non-compact groups and the development of methods for classifying their subgroups.[1] Sharp wrote a series of articles on generating functions in group representation theory.[7] Most of the known generating functions were calculated in papers written by Sharp and his collaborators.[2]
In 1994, a special issue of the Canadian Journal of Physics was dedicated to Sharp on the occasion of his 70th birthday.[1] Following his death, a Workshop on Symmetry in Physics was held at the Centre de Recherches Mathématiques, Université de Montreal, from September 12-14, 2002, with the Proceedings dedicated to Sharp's legacy.[8]
