An example of rotationally symmetric $Q_{n-1}$-translators and a non-existence theorem in $\mathbb{R}^{n+1}$

Abstract: The main result in this paper is a non-existence Theorem of entire $Q_{n-1}$-translators in $\mathbb{R}^{n+1}$. In addition, an example of non-entire complete $Q_{n-1}$-translator has been found and a Tangential Principle for $Q_k$-translators in $\mathbb{R}^{n+1}$.
