==Note 25==

Continuing with the example <math>pq : X \to \mathbb{B},</math> Figure&nbsp;25-1 shows the enlargement or shift map <math>\operatorname{E}(pq) : \operatorname{E}X \to \mathbb{B}</math> in the same style of differential field picture that we drew for the tacit extension <math>\varepsilon (pq) : \operatorname{E}X \to \mathbb{B}.</math>

Staying with the example pq : X -> B, Figure 25-1 shows

 

the enlargement or shift map E[pq] : EX -> B in the same

style of differential field picture that we drew for the

tacit extension !e![pq] : EX -> B.
