Abstract: We obtain sharp conditions guaranteeing that every non-negative weak solution of the inequality ∑|α|=m∂αaα(x,t,u)−ut⩾f(x,t)g(u)in R+n+1=Rn×(0,∞),m,n⩾1, stabilizes to zero as t→∞. These conditions generalize the well-known Keller–Osserman condition on the growth of the function g at infinity.
Keywords: Higher order evolution inequalities, nonlinearity, stabilization
