Boundedness in a three-dimensional attraction-repulsion
chemotaxis system with nonlinear diffusion and logistic source
Yilong Wang
Abstract:
This article concerns the attraction-repulsion chemotaxis system with
nonlinear diffusion and logistic source,

under Neumann boundary conditions in a bounded domain
with smooth boundary.
We show that if the diffusion is strong enough or
the logistic dampening is sufficiently powerful, then the corresponding
system possesses a global bounded classical solution for any sufficiently
regular initial data. Moreover, it is proved that if
,
and
for the latter case,
then
