Strict inner amenability for tensor product of Hopf-von Neumann algebras

In this paper for two Hopf-von Neumann algebras ${\Bbb H}_1=(\frak{M}_1,\Gamma_1)$ and ${\Bbb H}_2=(\frak{M}_2,\Gamma_2)$, we prove that if $\mathbb{H}_1$ is strictly inner amenable and either ${\mathbb{H}_2}$ is strictly inner amenable or predual of ${\frak{M}_2}$ has a bounded approximate identity, then tensor product of $\mathbb{H}_1$ and $\mathbb{H}_2$ is strictly inner amenable.
