Corollary 1

Let $\chi \in \mathsf{X}(A)$ and $\boldsymbol{a}\in A^n$. For every germ $f\in \mathscr{O}$(Sp$^n(\boldsymbol{a})$), one has $\chi (\Theta_{\boldsymbol{a}}(f)) =f(\chi (a_1), . . . , \chi (a_n))$.

This is a consequence of Proposition 3, applied to the continuous unital morphism $\chi : A\rightarrow \mathbf{C}$ (Theorem 1 of I, p. 29), and of the corollary to Proposition 2, applied to the Banach algebra $\mathbf{C}$.
