Abstract:

We obtain a necessary condition and a sufficient condition, both expressed in terms of Wiener type tests involving the parabolic $W_{q'}^{2,1}$- capacity, where $q'=\frac{q}{q-1}$, for the existence of large solutions to equation $\partial_tu-\Delta u+u^q=0$ in non-cylindrical domain, where $q>1$. Also, we provide a sufficient condition associated with equation $\partial_t u-\Delta u+e^u-1=0$. Besides, we apply our results to equation: $\partial_tu-\Delta u+a
\nabla u
^p+bu^{q}=0$ for $a,b>0$, $1<p<2$ and $q>1$.
