摘要:For the three-dimensional quasilinear wave equations under the null condition, global existence and pointwise decay for this model have been proved in the celebrated works of Klainerman and Christodoulou for small smooth initial data. In this talk, I will illustrate the precise pointwise asymptotic behavior of the solutions for initial data posed on a hyperboloid and show that the decay rate is optimal for a generic set of initial data. This is joint work with Siyuan Ma, Yue Ma, and Xu Yuan.
