Existence and non-existence of solutions for Hardy parabolic equations with singular initial data
We establish the existence, non-existence and uniqueness of the local solutions of the Hardy parabolic equation $u_t - \Delta u = h(t)|\cdot |^{-\gamma}g(u)$ on $\Omega \times (0,T) $ with Dirichlet boundary conditions. We assume that $\Omega$ with $0\in \Omega$ is a smooth domain bounded or unboun...

| Summary: | We establish the existence, non-existence and uniqueness of the local solutions of
the Hardy parabolic equation $u_t - \Delta u = h(t)|\cdot |^{-\gamma}g(u)$ on
$\Omega \times (0,T) $ with Dirichlet boundary conditions.
We assume that $\Omega$ with $0\in \Omega$ is a smooth domain bounded or unbounded,
$h \in C(0,\infty)$, $g \in C([0,\infty))$ is a non-decreasing function,
$0<\gamma<\min\{2,N\}$, and the initial data have a singularity at the origin. |
