- We consider a higher order in (time) semilinear evolution inequality posed on the Korányi ball under an inhomogeneous Dirichlet-type boundary condition. The problem involves an inverse-square potential $λ/|ξ|_\mathbb{H}^2$, where $λ\geq -(Q-2)^2/4$ and a general weight function $V$ depending on the space variable in front of the power nonlinearity. We first establish a general nonexistence result for the considered problem. Next, in the special case $V(ξ):=|ξ|_\mathbb{H}^a$, $a\in \mathbb{R}$, we prove the sharpness of our nonexistence result and show that the problem admits three different critical behaviors according to the value of the parameter $λ$.
