Ključne reči: nepokretna tačka, problem granične vrednosti, teorema nepokretne tačke tipa Leray-Schauder

Sažetak


Uvod/cilj: U radu se prikazuje postojanje generičke Grinove funkcije za problem granične vrednosti proizvoljnog reda koji se javlja kod mnogih pojava konvekcije toplote u, na primer, atmosferi, okeanima i na površini Sunca.

Metode: Koristi se teorema nepokretne tačke tipa Leray-Schauder kako bi se utvrdilo postojanje nepokretne tačke u navedenom problemu.

Rezultati: Prikazano je rešenje za proizvoljan red problema. Predloženi su neki praktični primeri.

Zaključak:  Granični problem ima rešenje za proizvoljni n-ti red.
