nLab quasinormal mode


Quasinormal modes are analogues of normal modes for physical systems in the presence of dissipation. In other words, these are the eigenstates of linearized equations of motion, e.g. of nonlinear wave equations. The eigenvalues become complex, signifying nonconservation of energy. This notion is especially prevalent recently in black hole physics.
