| contents | Giga and Kohn studied the blowup solutions for the equation $v_{t} - Δv - |v|^{p - 1} v = 0 $ and characterized the asymptotic behavior of $v$ near a singularity. In the proof, they reduced the problem to a Liouville theorem for the equation $Δu - \frac{1}{2} x \cdot \nabla u + |u|^{p - 1} u - βu = 0$ where $β= \frac{1}{p - 1}$ and $|u|$ is bounded. This article is a remark for their work and we will show when $u \geq 0$, the boundedness condition for $|u|$ can be removed. |
