Spatiu metric

Post by Beniamin Bogosel »

Fie \( (X,d) \) un spatiu metric si \( \mathcal T \) topologia indusa de metrica \( d \). Demonstrati ca \( \sigma \)-algebra generata de \( \mathcal T \) coincide cu clasa monotona generata de \( \mathcal{T} \).
Yesterday is history,

But today is a gift.
That's why it's called present. :)
