A quasilinear equation is one that is linear in all but the terms involving the highest order derivatives (whether they are of fractional order or not). For instance, the following equations are quasilinear
\[ \mbox{div} \left ( \frac{\nabla u}{\sqrt{1+|\nabla u|^2}}\right ) = 0 \] \[ u_t = \mbox{div} \left ( u^p \nabla u\right ) \] \[ (-\Delta)^{s}+H(x,u,\nabla u)=0 (s>1/2) \]
