Attachment 'balint_1.txt'
DownloadDobry den,
posielam riesenie premioveho prikladu z dnesnej prednasky:
Najdite take mnoziny Ai pre i patri I take, ze prienik Ai pre i z I je prazdna
mnozina a zaroven pre vsetky mnoziny F, kde F je konecnou podmnozinou I je
prienik Ai pre i z F neprazdna mnozina.
Ai = {x je prvkom N: x != i}
Ak vyberieme konecny pocet mnozin, ich prienikom bude neprazdna mnozina, napr:
A2 prienik A5 prienik A10 = N - {2,5,10}
Prienikom vsetkych mnozin Ai je prazdna mnozina, pretoze neexistuje take x z N,
ktore patri do vsetkych mnozin Ai (vzdy v jednej bude chybat).
