Nonexistence of blow-up solutions with smooth radiation for energy-critical equivariant wave maps

Jacek Jendrej, Yuchen Yin, Lifeng Zhao

We study $k$-equivariant energy critical wave maps ${\mathbb{R}}^{1+2}\to {\mathbb{S}}^2$, for any equivariance degree $k\ge 2$. We prove that the radiation associated with any finite…
