Partial regularity for degenerate parabolic systems with non-standard growth and discontinuous coefficients
Qifan Li
This article studies the partial Hölder continuity of weak solutions to certain degenerate parabolic systems whose model is the differentiable parabolic -Laplacian system,…
Higher integrability for obstacle problem related to the singular porous medium equation
Qifan Li
This paper is concerned with the self-improving property for obstacle problem related to the singular porous medium equation. We establish a local higher integrability result for t…
On the continuity of solutions to doubly singular parabolic equations
Qifan Li
This paper considers a certain doubly singular parabolic equations with one singularity occurs in the time derivative, whose model is \begin{equation*} \partial_tβ(u)-\operatorname…
Weak Harnack estimates for supersolutions to doubly degenerate parabolic equations
Qifan Li
We establish weak Harnack inequalities for positive, weak supersolutions to certain doubly degenerate parabolic equations. The prototype of this kind of equations is $$\partial_tu-…
Littlewood-Paley characterization for spaces
Qifan Li
In Baraka's paper [2], he obtained the Littlewood-Paley characterization of Campanato spaces and introduced spaces. He showed that $\mathcal {L}^{2…
