Matematiska kollokviet

Wednesday 24 February 2010, Glashuset 13.15-14.15, Prof. Sergey Nazarov, Institute of Mechanical Engineering Problems, St. Petersburg.

Title: The continuous spectrum of peak-shaped elastic bodies ("Vibrating Black Holes")

Abstract: It will be shown that the continuous spectrum of a peak-shaped elastic body can be non-empty that provokes for the wave propagation phenomenon in a finite volume (note that the spectrum of a finite body with a Lipschitz boundary is always discrete). This fact is used for creating so-called Vibrating Black Holes which have become a tool for the effective absorption of sound and elastic vibrations. Open questions in the spectral theory of elastic solids will be formulated.

Friday 5 March 2010, Glashuset 13.15-14.15, Margaret Beck, Boston Univesity.

Course of lectures

TM's guest Professor Sergey Nazarov is planning to give a course of lectures on "Asymptotic methods in elasticity and fluid mechanics" during his stay here. In his first visit in February and March he will give a series of lectures on "Integral characteristics of defects". This will take place in Glashuset (except 26/2, 5/3 and 26/3, in these days it will be in Kompakta rummet), every Friday, at 11-12 and include the following lectures:

1. Integral characteristics of harmonics in exterior domains
2. Theory of elasticity. Tensor and matrix notation.
3. Polarization matrix of a defect in an elastic space.
4. Properties of the polarization matrix.
5. Asymptotic formulas for the energy functionals.
6. Justification procedures.
7. The Eshelby theorem and the optimization of a patch.
8. Damage tensor and damage measures.
