Moze li neko da mi da konkretnu definiciju i neki mali primercic primene ove teoreme. Dolazi u obzir i neki link, ali ja nisam uspeo da pronadjem nista korisno.

-NATO is bombing Serbia, a Yugoslavian republic, to stop the Serbs from forcing ethnic Albanians from Kosovo. Serb supporters sock it to NATO, U.S. Web sites. Magis says NATO headquarters won't launch an electronic counterstrike. "We want to show we're more civilized," he says. "We believe in freedom of speech." NATO is even discussing the possibility of hosting Serbian information on the Web so the Serbs can share their views.

Inace (cisto da kazem jos nesto) ova teorema je nesto slicno kao Kejlijeva s tim sto se koristi za neoznacene grafove - odnosno za njihovo prebrojavanje.
Ajde ljudi, pomagajte!

Pa slabo, samo sam u onom radu "Isomers, Groups, and Combinatorics" nasao ono sto mi treba dok ostali nesto tupe do besvesti - meni konkretno treba primena kod racunanja broj izomera, cak sam na mathforum-u nasao sledece (neki lik pita):

Citat:

Has anyone heard of a proof of polya's theorem ??

It says that the number of zeros of the heat equation with periodic
intial data of period 1 can only decrease with time .
Any ideas of proof ?

gde li je ovo iskopao....svaka mu cast? (da je to rekao mojoj profesorki hemije onesvestila bi se)

Citat:

pirgos_madden: samo sam u onom radu "Isomers, Groups, and Combinatorics" nasao ono sto mi treba

Pa dobro....nisam trebao ovo da kazem, iz razloga sto su svi verovatno shvatili ovo kao pomoc odnosno da je to sve sto mi treba, ali nije tako. Dakle u tom radu ima neceg ali nedovoljno i neprakticno - dakle u stilu kao da cu celog zivota da se bavimn topologijom i teorijom grafova.
Moje pitanje je konkretno i vise ne vazi ono:

(moze vaziti samo ako je nesto stvarno ok). Ako neko zna da mi objasni ovu teoremu i neku primenu nek to uradi u suprotnom hvala svima koliko vas ima ... i to je to.
