On the weak Harnack inequality for unbounded non-negative super-solutions of degenerate double-phase parabolic equations

Abstract: In the case $q> p\dfrac{n+2}{n}$, we give a proof of the weak Harnack inequality for non-negative super-solutions of degenerate double-phase parabolic equations under the additional assumption that $u\in L^{s}{loc}(\Omega{T})$ with some $s >p\dfrac{n+2}{n}$.
