Null-condition well-posedness conjecture. If the null condition holds, then (GNLW) is well-posed in $H^s\times H^{s-1}$ for some $s<\frac n2+\frac34$ when $n=2$, respectively for s…

Let $u$ solve a quasilinear wave system of the form … with the weak null condition (WNC) defined by the existence of a global asymptotic-PDE solution for the ansatz … whose derivat…
