Abstract:This paper addresses the analysis of the weak solution of urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0001 in a bounded domain Ω subject to the boundary condition urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0002 on urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0003, when the data f belongs to urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0004 and urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0005. We prove existence and uniqueness of solution for this problem in the Nikolskii space urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0006. Moreover, we obtain energy estimates regarding the Nikolskii norm of ω in terms of the urn:x-wiley:dummy:mana201200099:equation:mana201200099-math-0007 norm of f.
