This paper deals with the quasilinear Keller-Segel system
$ \begin{align*} \begin{cases} u_t = \nabla\cdot(D(u)\nabla u)-\nabla\cdot(S(u)\nabla v), &x \in \Omega, \ t>0, \\ \ v_t = \Delta v - v +u, &x \in \Omega, \ t>0 \end{cases} \end{align*} $
in
$ \Omega = \mathbb{R}^N $
 or in a smoothly bounded domain
$ \Omega\subset \mathbb{R}^N $
, with nonnegative initial data
$ u_0\in L^1(\Omega) \cap L^\infty(\Omega) $
, and
$ v_0\in L^1(\Omega) \cap W^{1, \infty}(\Omega) $
; in the case that
$ \Omega $
 is bounded, it is supplemented with homogeneous Neumann boundary condition. The diffusivity
$ D(u) $
 and the sensitivity
$ S(u) $
 are assumed to fulfill
$ D(u)\ge u^{m-1}\ (m\geq1) $
 and
$ S(u)\leq u^{q-1}\ (q\geq 2) $
, respectively. This paper derives uniform-in-time boundedness of nonnegative solutions to the system when
$ q<m+\frac{2}{N} $
. In the case
$ \Omega = \mathbb{R}^N $
 the result says boundedness which was not attained in a previous paper (J. Differential Equations 2012; 252:1421-1440). The proof is based on the maximal Sobolev regularity for the second equation. This also simplifies a previous proof given by Tao-Winkler (J. Differential Equations 2012; 252:692-715) in the case of bounded domains.
Keywords: Quasilinear degenerate Keller-Segel systems, boundedness.
