Professor Gary Gibbons FRS
Gary Gibbons has made important contributions to general relativity and the quantum theory of gravity. He played a leading role in the development of the Euclidean approach to quantum gravity and showed how it could be used to understand the thermal character of black holes and inflating universes. This revealed a deep and unexpected relationship between gravitation and thermodynamics. As part of the Euclidean quantum gravity programme, he discovered many of the known gravitational instantons and classified their properties. In the more conventional Lorentzian approach to gravity, he has studied the behaviour of solitons in gauge theories and general relativity and has shown how supersymmetry leads to Bogomolny inequalities on the masses and charges. More recently, he has been investigating the role of topology in gravity and has obtained important restrictions on how the topology of space–time can change.
