报告摘要:



In this talk, I will give a brief introduction on the mathematical relativity and developments of the cosmology in mathematical perspective. I will first focus on the fully nonlinear stability problem of Friedmann-Lemaître-Robertson-Walker (FLRW) solutions to the Einstein-Euler system (future stability with positive cosmological constant and past stability which is also known as the big bang stability), then turn to problems of cosmological Newtonian limits. Since the solutions are fully nonlinear, they surely include complete gravitational waves and hopefully, these mathematical models could inspire you to find some connections with the problems physicists are currently interested in.
