Global low regularity solutions for nonlinear elastic waves
Kunio Hidano, Dongbing Zha
We study the Cauchy problem for 3-D nonlinear elastic waves satisfying the null condition with low regularity initial data. In the radially symmetric case, we prove the global exis…

Space-time estimates, regularity and almost global existence for elastic waves
Kunio Hidano, Dongbing Zha
In this paper, we first establish a kind of weighted space-time estimate, which belongs to Keel-Smith-Sogge type estimates, for perturbed linear elastic wave equations. This…
