Query: Stable estimates for source solution of critical fractal Burgers
  equation   In this paper, we provide two-sided estimates for the source solution of
$d$-dimensional critical fractal Burgers equation $u_t-\Delta^{\alpha/2}+b\cdot
\nabla\left(u|u|^q\right)=0$, $q=(\alpha-1)/d$, $\alpha\in(1,2)$,
$b\in\mathbb{R}^d$, by the density function of the isotropic $\alpha$-stable
process.
