We derive uniform in time L∞-bound for solutions to an aggregation-diffusion model with attractive-repulsive potentials or fully attractive potentials. We analyze two cases: either the repulsive nonlocal term dominates over the attractive part, or the diffusion term dominates over the fully attractive nonlocal part. When the repulsive part of the potential has a weaker singularity (2 − n≤ B< A≤ 2), we use the classical approach by the Sobolev and Young inequalities together with differential iterative inequalities to prove that solutions have the uniform in time L∞-bound. When the repulsive part of the potential has a stronger singularity (− n< B< 2 − n≤ A≤ 2), we show the uniform bounds by utilizing properties of fractional operators. We also show uniform bounds in the purely attractive case 2 − n≤ A≤ 2 within the diffusion dominated regime.
