Paul Dirac and the Pervasiveness of His Thinking
David I Olive
I shall use a few personal reminiscences of my time as a student and colleague of Dirac in Cambridge to introduce some reflections on the nature of research in theoretical physics.…
Duality and Lorentzian Kac-Moody Algebras
David Ian Olive
A review is given of ideas in electromagnetic duality and connections to integrable field theories with soliton solutions. This leads on to a summary of recent work on Lorentzian a…
The Principal SO(1,2) Subalgebra of a Hyperbolic Kac Moody Algebra
H. Nicolai, D. I. Olive
The analog of the principal SO(3) subalgebra of a finite dimensional simple Lie algebra can be defined for any hyperbolic Kac Moody algebra g(A) associated with a symmetrizable Car…
The Quantisation of Charges
David I Olive
The question as to whether the integrality of the spectrum of observed electric charges is due to a quantum effext has fascinated theoretical physicists throughout the last century…
Spin and Electromagnetic Duality: An Outline
David I Olive
An outline is given of recent work concerning the electromagnetic duality properties of Maxwell theory on curved space-times with or without spin structures.
