Serii absolut convergente

Post by Alin Galatan »

Stim ca intr-o serie absolut convergenta, putem permuta termenii si obtinem o serie convergenta la aceeasi limita.
Reciproc, daca stim ca pt. o serie convergenta, oricum am permuta termenii obtinem o serie convergenta la aceeasi limita, atunci seria noastra e absolut convergenta?
