 Dersin Dili Türkçe Dersin Seviyesi Yüksek Lisans Dersin Türü SECMELI Dersin Koordinatörü Dr.Öğr.Üyesi BAHAR DEMİRTÜRK BİTİM Dersi Verenler Dersin Yardımcıları Research asistants of mathematics department Dersin Kategorisi Dersin Amacı Introducing Diophantine equations and finding the answer of the question" Is given Diophantine equation be solvable? If it is solvable, are its solutions finite or infinite? What are the all solutions of this equation?". All solutions of Diophantine equations will be obtained by different methods, with uzing number theory and algebra knowledge. Moreover our aim is investigating the relation between Fibonacci-Lucas numbers and Diophantine equations, Pell-Pell Lucas numbers and Diophantine equations. Dersin İçeriği Definition of Diophantine equations, elementary Methods for Solving Diophantine equations; The Factoring Method, using Inequalities, the parametric method, the modular arithmetic method, the method of mathematical induction, Fermats method of infinite descent, some classical Diophantine equations; linear Diophantine equations, Pythagorean triples and related problems, Pell-Type equations, solving Pells equation, the equation , some advanced methods for solving Diophantine equations; the ring of Gaussian integers, the ring of integers of , Quadratic Reciprocity and Diophantine equations, divisors of certain forms such as a^2+b^2, a^2+2b^2 and a^2-2b^2.
