Uniqueness of weak solutions to a Keller–Segel–Navier–Stokes system

Abstract This paper proves some uniqueness results of weak solutions to a Keller–Segel–Navier–Stokes system in a bounded domain Ω ⊂ R N ( N ≥ 3 ) under some conditions. As a by-product, we show that these conditions hold true when N = 2 for the Keller–Segel–Navier–Stokes system with a logistic term.
