| Citation | Edward Corrigan has made many distinguished contributions to gauge theories and string theories of elementary particles and to related aspects of mathematical physics. His early work laid many of the foundations of the modern theory of superstrings He was one of the first to explore the properties of the magnetic monopole soliton-like objects, which necessarily occur in many gauge theories of elementary particles, and generalised the classic relation between electric and magnetic charges found by Dirac. He pioneered the construction of multi-instanton solutions to gauge theories and also found expressions for Green functions in their background. His work is characterised by the ability to combine the use of modern mathematical ideas with explicit calculations. In particular, he has illuminated our understanding of how topological and group-theoretic ideas can be used to analyse the structure of quantum field theories. Recently he has obtained beautiful results on the quantum field theory of certain systems whose integrability was previously understood at the classical level only. |
