This paper concerns the existence of bounded classical solutions to the attraction-repulsion chemotaxis system with logistic source(⋆) in a smooth bounded domain , subject to nonnegative initial data and homogeneous Neumann boundary conditions, where for all with some and . Here as well as γ and δ are positive constants. It is proved that the corresponding system possesses a unique global bounded classical solution in the balance case with or, the attraction domination case with and , respectively. The study of this paper improves the results in Li-Xiang (2016) [12], Xu-Zheng (2018) [39], Wang (2016) [26] as well as Zhao et al. (2017) [42] and Tello-Winkler (2007) [23], in which, the assumption (see Li-Xiang (2016) as well as Wang (2016) and Zhao et al. (2017)) or (see Tello-Winkler (2007)) or (see Xu-Zheng (2018)) or (see Li-Xiang (2016)) are intrinsically required.
