Abstract
In this paper, we study the existence and regularity results for some parabolic equations with degenerate coercivity, and a singular right-hand side. The model problem is
where \(\Omega \) is a bounded open subset of \(\mathbb{R}^{N}\) \(N\geq 2\), \(T>0\), \(\Lambda \in [0,p-1)\), \(f\) is a non-negative function belonging to \(L^{m}(Q_{T})\), \(Q_{T}=\Omega \times (0,T)\), \(\partial Q_{T}=\partial \Omega \times (0,T)\), \(0\leq \theta < p-1+\frac{p}{N}+\gamma (1+\frac{p}{N})\) and \(0\leq \gamma < p-1\).
