This event aims to bring together mathematicians interested and working in various types of problems where spectral bands and spectral gaps
play a role. This includes
- perturbation theory for eigenvalues, essential spectrum, spectral subspaces of (self-adjoint) operators,
- in particular of: Dirac, Schrödinger, and more general elliptic second order differential operators
- variational principles for eigenvalues
- periodic operators, generalised Fourier transform, direct integral decomposition
- periodic partial differential equations, in particular Schrödinger operators, Floquet-Bloch theory, dispersion relations
- perturbation of periodic models, in particular random ones
- homogenisation of elliptic problems
