Strong Cosmic Censorship Versus Λ - IPAM at UCLA

Institute for Pure & Applied Mathematics (IPAM) via YouTube

Overview

Explore the fundamental open problem of strong cosmic censorship in classical general relativity through this 40-minute conference talk by Mihalis Dafermos of Princeton University. Delve into the challenges posed to the conjecture by rotating black holes and the unexpected impact of a non-zero cosmological constant. Examine the intricate mechanisms that support the conjecture's validity, including subtle aspects of black hole scattering theory and, surprisingly, number theory in the case of negative cosmological constant. Gain insights into the Schwarzschild solution, blue shift and dispersion phenomena, and the implications of positive cosmological constant. Analyze the linear formulation, sustainable formulation, and the interplay between rough and smooth elements in this complex problem. Evaluate whether strong cosmic censorship can withstand the challenge of non-zero Λ and understand its implications for the deterministic nature of general relativity.
