We construct global generalized solutions to the chemotaxis system
$ \begin{cases} u_t = \Delta u - \nabla \cdot (u \nabla v) + \lambda(x) u - \mu(x) u^\kappa, \\ v_t = \Delta v - v + u \end{cases} $
in smooth, bounded domains
$ \Omega \subset \mathbb R^n $
,
$ n \geq 2 $
, for certain choices of
$ \lambda, \mu $
and
$ \kappa $
.
Here, inter alia, the selections
$ \mu(x) = |x|^\alpha $
with
$ \alpha < 2 $
and
$ \kappa = 2 $
as well as
$ \mu \equiv \mu_1 > 0 $
and
$ \kappa > \min\{\frac{2n-2}{n}, \frac{2n+4}{n+4}\} $
are admissible (in both cases for any sufficiently smooth
$ \lambda $
).
While the former case appears to be novel in general, in the two- and three-dimensional setting, the latter improves on a recent result by Winkler (Adv. Nonlinear Anal. 9 (2019), no. 1,526–566), where the condition
$ \kappa > \frac{2n+4}{n+4} $
has been imposed. In particular, for
$ n = 2 $
, our result shows that taking any
$ \kappa > 1 $
suffices to exclude the possibility of collapse into a persistent Dirac distribution.
