$A \subseteq \mathbb{F}$ is a finite subset. $V^n_d$ is the vector space of polynomials in $n$ variables of degree at most $d$. $\mathbb{F}^A$ is the vector space of functions $f : A \rightarrow \mathbb{F}$. The following is called something with "evaluation," but I don't know what it means..? $e_A : V^n_d \rightarrow \mathbb{F}^A$, $$e_A(p) = (p(a))_{a \in A}$$ I think it's just the $_{a \in A}$ part i don't get
