Hugh Osborn FRS University of Cambridge , Department of Applied Mathematics and Theoretical Physics .
He is known for his work on Conformal Field Theory and Quantum Field Theory .
Education [ edit ]
Osborn obtained his PhD in 1967 from the University College London . His PhD advisor was Sigurd Zienau .
Career and research [ edit ]
After postdoctoral research positions at the University of Sussex and Queen Mary University of London , he became a professor first at the University of Glasgow and then in 1971 moved to the University of Cambridge where he remained ever since.[1] Trinity College . In April 2020 he was elected a Fellow of the Royal Society .[2]
In 1989, Osborn [3] C-theorem , which was conjectured one year earlier by John Cardy . Osborn's proof was applicable to renormalization group flows which are perturbative, that is do not deviate far from the free quantum field theories , and was valid to all orders in perturbation theory . It provided a strong hint that the four-dimensional C-theorem must be universally valid, but a nonperturbative proof of this fact was found only in 2011 by Zohar Komargodski and Adam Schwimmer .
In 2001 and 2004, Osborn, in collaboration with Francis Dolan , obtained explicit expressions for the conformal blocks in four dimensional conformal field theories .[4] conformal bootstrap approach to conformal field theories .
