Algebra von Neumann comutativa pe un spatiu Hilbert

Post by Cezar Lupu »

Sa se arate ca o algebra von Neumann comutativa pe un spatiu Hilbert separabil este generata de un singur operator autoadjunct.
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.
