A memorial meeting to mark the life and work of
Professor W.N. Everitt
This meeting, to be held on the 15-17 May, 2014, is a memorial to Norrie Everitt FRSE, a distinguished expert in the field of spectral analysis and differential equations who died on 17 July, 2011 aged 87.
Norrie was a widely acknowledged authority on the spectral theory of differential equations, and inequalities. He made many significant contributions to such topics as the Titchmarsh-Weyl m-function, the deficiency index problem, periodic problems, and the numerical computation of eigenvalues of Sturm-Liouville problems.
The meeting will focus on the following topics:
- ordinary differential equations: selfadjoint and non-selfadjoint Sturm-Liouville operators, inverse problems;
- systems of differential equations: Dirac operators and other block operator matrices;
- non-linear differential equations;
- periodic differential operators and the structure of their spectrum.
