Sommario:
- Over an algebraically closed field $\mathbb{F}$ of zero characteristic polynomial map $ξ: \mathbb{F}^n\rightarrow \mathbb{F}^n$ of the form $ξ(x)=x-((xA_1)^{3}, (xA_2)^{3},..., (xA_n)^{3})$, where $x=(x_1,x_2,...,x_n)$ a row vector of variables, $A_i\in \mathbb{F}^n$ are column vectors, is considered. It is shown that if $\det(\partialξ(x))=1$, then $ξ$ is injective.
