On critical exponents for weak solutions to the Cauchy problem for one
nonlinear equation with gradient non-linearity
Abstract
In this paper, we consider the Cauchy problem for one nonclassical,
third-order, partial differential equation with gradient non-linearity
$|\nabla u(x,t)|^q$. The solution
to this problem is understood in a weak sense. We show that for
$1“3/2$ the existence of the only local-in-time weak solution of
Cauchy’s problem.If $3/2”
