Abstract In the paper we consider semilinear parabolic equation with a nonlinear term ε f ( u ) {\varepsilon f(u)} , whose trajectories undergo impulsive perturbations when they meet the impulsive set M = { ∥ u ∥ = R } {M=\{\|u\|=R\}} . We prove that for sufficiently small ε this problem generates an impulsive dynamical system which possesses a compact uniform attractor in the phase space L 2 {L^{2}} .
