Pointwise estimates of solutions to the weighted porous medium equation and the fast diffusion one via weighted Riesz potentials
Keyword(s):
For the weighted parabolic equation $$ \ v\left(x \right)u_{t} - {div({\omega(x)u^{m-1}}} \nabla u) = f(x,t)\: ,\; u\geq{0}\:,\; m\neq{1}, $$ we prove the local boundedness of weak solutions in terms of the ${\;}$ weighted Riesz potential on the right-hand side of the equation.
