Conference: Kent Spectral Theory

Held at SMSAS 14-17 April 2014.

Supported by University of Kent Faculty of Sciences, the London Mathematical Society, European Union Marie Curie Action.

During the last few decades operator theory and its applications in various fields, such as hydrodynamics, quantum mechanics, quantum optics, and quantum field theory have been a quickly developing branch of mathematics. This area is strongly influenced by modern analysis, including modern real and complex analysis.

One particular new development is the interaction between classical selfadjoint operator theory and modern non-selfadjoint operator theory, two areas which previously had little overlap. This was a key area that this conference focused on.

The idea of the conference was to promote exchange of information between international experts and people in the UK working in different areas of operator theory and analysis. The expectation was that this will be fruitful for both of these branches of mathematics, pointing ways forward to new research questions.

To help the development of young researchers working in the field there was a special session for talks by research students and some financial support was able to made available for research students.
