Multime perfecta

Post by Beniamin Bogosel »

Demonstrati ca o multime perfecta din \( \mathbb{R}^k \) este nenumarabila.

(O multime perfecta este o multime inchisa si fiecare punct al sau este punct limita.)

Ma intereseaza daca exista o solutie mai frumoasa ca cea din W. Rudin, Principles of Mathematical Analysis
Yesterday is history,
Tomorow is a mistery,
But today is a gift.
That's why it's called present. :)
