Alta serie divergenta de numere prime

Post by Cezar Lupu »

Daca prin \( p_{n} \) se noteaza al \( n \)-lea numar prim, atunci seria

\( \sum_{n \ge 1} \frac{n}{p_{p_{n}} \) este divergenta.

Dan Radu, GMA 1973
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says “You’re all idiots”, and pours two beers.
