teorema Whitney "forma usoara"

Post by Cezar Lupu »

Sa se arate ca orice varietate compacta \( n \)-dimensionala se imerseaza in \( \mathbb{R}^{2n} \) si se scufunda in \( \mathbb{R}^{2n+1} \).
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.
