Abstract:
We prove the higher integrability of the gradient of solutions of the Zaremba problem in a bounded strongly Lipschitz domain for an inhomogeneous $p(\,\cdot\,)$-Laplace equation with a variable exponent $p$ having a logarithmic continuity modulus.
The results in Sec. 3 belong to the first
author. The proof of Lemma 1 and Theorem 1 of that
section was supported by a grant from the Russian Science Foundation
(project No. 22-21-00292), and the proof of Theorem 2 was
supported by the State Assignment of the Vladimir State University
(FZUN-2023-0004). The results of the second author in
Sec. 2 were supported by a grant of the Russian Science
Foundation (project No. 20-11-20272); and those in Sec. 1,
by the grant from the Committee of Science of the Ministry of
Science and Higher Education of the Republic of Kazakhstan (project
AP14869553).
