The class will cover various aspects of the theory of spectral, linear and nonlinear stability of special solutions to partial differential equations. As a first ingredient, the spectral theory of linear operators will be developed, including point and essential spectrum for self-adjoint, compact and locally compact operators and their perturbations, properties of the resolvent and Riesz projections, Kato-Rellich and Weyl theorems. Several important examples will be studied in the second part of the class, including linear stability of pulses in dissipative systems, stability of waves in Hamiltonian equations and the relation between linear and nonlinear stability. This will be done by introducing a variety of contemporary tools such as the Fredholm properties and exponential dichotomies of the operators, the Evans function and several decomposition techniques.
