Date/Time: 18 November 2009, 16:30 Venue: Room 505, Mathematics Department Title: Periodicity at work Abstract Partial differential equations with periodic coefficients have been of overwhelming importance in Mathematics for over a century. This is partly due to their mathematical beauty, and partly due to their relevance to important real life processes: for example the electrical conductivity of metals, properties of crystals, wave propagation and many others. A large number of new results in this field, including the resolution of some long-standing conjectures, were obtained in the last two or three decades. I intend to describe some fundamental mathematical ideas behind periodic problems, and to give a short survey of the recent results.
