In this paper we study the chemotaxis–Stokes system with slow -Laplacian diffusion and rotation: , , and in a bounded domain with , subject to the Neumann–Neumann–Dirichlet boundary conditions, where , and are given sufficiently smooth functions with bounded in , for with , and nondecreasing function . It is proved that the problem possesses a globally bounded weak solution provided and . This extends the current global boundedness result by Tao and Li (2020), where the case of was well solved. It is mentioned that, without constructing coupled energy functionals, the technique used in the present paper is somewhat different.
