David Edmunds is an analyst who has been at the University of Sussex since 1966 where he is currently Emeritus Professor. His interests include function spaces, interpolation theory, entropy and s-numbers, and elliptic partial differential equations. Desmond Evans is Emeritus Professor at the University of Cardiff, having been at Cardiff since 1964. His main research interests are in the spectral theory associated with differential equations and related areas of analysis and mathematical physics. These related areas include the properties of function spaces and the mappings between them, growth and asymptotic estimates for eigenvalues and s-numbers, and inequalities.
