Abstract
We study the co-rotational Beris-Edwards system modeling nematic liquid crystals and revisit the eigenvalue preservation property discussed in \cite{XZ16}. We give an alternative but direct proof to the eigenvalue preservation of the initial data for the -tensor. It is noted that our proof is not only valid in the whole space case, but in the bounded domain case as well.
