Canonical name for the partition that a partition of a set induces on its subsets

29 Views Asked by At

Assume we have a partition $\mathcal{F}$ of a set $E$ and $X\subset E$ is there a canonical name for

$$\mathcal{G} = \{X\cap A|A\in \mathcal{F}\} $$

?

I'd say induced partition but it is a bit of a mouthful, or trace, borrowing from filters/filtrations, but I'd like to know if it already has another name.

Bonus points : if $X\not\subset E$, how would you call

$$\mathcal{G}' = \{X\cap A|A\in \mathcal{F}\} \cup \{\{x\}|x\in X\smallsetminus E\}$$

?


If anyone wonders where this comes from, the notion appears in some clustering quality metrics for NLP
