Puasono dvimatės lygties vidinių reikšmių uždavinio sprendimas „tilto“ funkcijų metodais / Solution of Poisson two-dimentional equation internal values' task by "brige" function approaches

Tutkienė, Simona 03 August 2011 (has links)
Magistro darbe matematiniu modeliavimu nagrinėjamas Puasono lygties sprendimo efektyvumas naujais metodais. Šiame darbe siūloma spręsti šias lygtis naudojant vadinamąsias „tilto“ funkcijas. Bandomos dviejų rūšių „tilto“ funkcijos: hiperbolinio tangento ir trigonometrinės. Puasono lygties sprendinys ieškomas per „tilto“ funkcijų ir polinomų sandaugų sumą. / In this study Poisson function is solved using “bridge” functions method, meaning that all range is divided to separate zones (“bridges”) and to separate approximation polynomial multiplied of “bridge” functions. Common solution is equal to the sum of separate polynomial multiplied of “bridge” functions. To solve Poisson equation, the so-called "bridge" function was used. Differential equation, the solution we were looking via the "bridge" functions and products of powers of polynomials amount.
