The HADES seminar on Tuesday, December 16th, will be at 3:30pm in Room 762.

Abstract: The classical wave equation is a basic model for the propagation of waves. In even space dimensions, solutions are known to develop long-lived polynomially decaying tails inside the region where the wave has passed, in contrast with the sharp finite propagation of disturbances in odd dimensions.

In this talk, I will discuss how such even-dimensional tails behave in the presence of forcing and nonlinear effects, as well as on non-stationary spacetime backgrounds.
