Dalhousie-AARMS AAMP Seminar: Peter Hintz (MIT)
Title: Linear stability of slowly rotating Kerr spacetimes Abstract: I will describe joint work with Dietrich Häfner and András Vasy in which we study the asymptotic behavior of linearized gravitational perturbations of Schwarzschild or slowly rotating Kerr black hole spacetimes. We show that solutions of the linearized Einstein equation decay at an inverse polynomial rate to a stationary solution (given by an infinitesimal variation of the mass and angular momentum of the black hole), plus a pure gauge term. The proof uses a detailed description of…

Aiden Bruen 80th Birthday Geometry Conference
This conference is in celebration of Professor Aiden Bruen's 80th birthday, to acknowledge and honour his contributions to finite geometry, design theory, coding theory, and combinatorics in general. Professor Bruen has had a tremendous impact in these areas, publishing dozens of highly cited articles. including but certainly not limited to Inventiones Mathematicae, Journal of Combinatorial Theory, Series A, Journal of Combinatorial Designs, and Designs, Codes and Cryptography. Professor Bruen is also an author of Cryptography, Information Theory, and Error Correction:…
