(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Conjecture: If K=a union of subsets of G with K open then each subset in the union is open

3. The attempt at a solution

Can't really see the proof. In fact it's false as any non discrete topology have open sets which are a union of subsets whch may not be open.
