ABSTRACT
This paper determines the critical mass for the attraction–repulsion chemotaxis system: ,
,
, subject to the non-flux boundary condition in a bounded domain
with
,
. It was known that the solutions are globally bounded if
. In this paper, we prove with
that the solutions must be globally bounded whenever the initial mass
, and the finite time blow-up may occur if
