Finite time blow up for systems of wave equations with multiple speeds posed on asymptotically Euclidean manifold
Mengyun Liu
In this work, we study the finite time blow-up phenomenon of three types of semilinear wave systems with multiple speeds, posed on asymptotically Euclidean manifolds. We establish…

Global existence for some 4-D quasilinear wave equations with low regularity
Mengyun Liu, Chengbo Wang
In this paper, we prove the global existence for some 4-D quasilinear wave equations with small, radial data in . The main idea is to exploit local energy estima…
