Description

The module is intended to give students a brief introduction to the spectral theory of operators in Banach and Hilbert spaces and then concentrate on practical applications to spectral geometry of the Dirichlet and Neumann Laplacians in the Euclidean spaces.
By the end of the module students are expected to be able to identify and demonstrate understanding of main definitions in spectral theory; formulate and solve problems involving bounded and unbounded operators; apply those to boundary value problems for some simple second order ordinary and partial differential operators.
Students will understand the links between abstract analysis, applications in physics, and numerical techniques
