Quantum Graphs, Their Spectra and Applications


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

2nd April 2007 to 5th April 2007

Workshop Theme

Analysis on graphs and other discrete structures has been developing for quite some time, in particular due to applications to number theory, algebra, probability theory, spectral geometry, as well as to its usefulness in many practical problems. New objects, so called quantum graphs have emerged recently. These are graphs considered as one-dimensional CW-complexes and equipped with differential or pseudo-differential, rather than customary difference operators. This has happened due to numerous new applications arising in several areas of mathematics, sciences, and engineering, e.g. in nanotechnology, microelectronics, quantum chemistry, superconductivity, optics, etc. Such graphs, besides being in many cases useful low-dimensional models of complex systems, are also used as toy models for studying difficult issues such as Anderson localisation and quantum chaos. The methods used or expected to be useful in analysis on quantum graphs come from a very wide range of topics: algebra, combinatorics, PDEs, spectral theory, micro-local and complex analysis, to name a few.

The workshop will assemble a diverse group of mathematicians and physicists working in or interested in entering this fast developing and fascinating area. Research students and postdocs are encouraged to apply.
