Gradient higher integrability for singular parabolic double-phase systems

Wontae Kim, Lauri Särkiö

We prove a local higher integrability result for the gradient of a weak solution to parabolic double-phase systems of $p$ -Laplace type when $\frac{2 n}{n + 2} < p \leq 2$ . The result is…

Lipschitz truncation method for parabolic double-phase systems and applications

Wontae Kim, Juha Kinnunen, Lauri Särkiö

We discuss a Lipschitz truncation technique for parabolic double-phase problems of $p$ -Laplace type in order to prove energy estimates and uniqueness results for the Dirichlet prob…
