Bu çalışmada, singüler pertürbe Volterra integro-diferansiyel denklemlerin yaklaşık çözümü için nümerik integrasyon yöntemi uygulanır. İlk olarak düzgün bir şebeke üzerinde sonlu fark metodu ile başlanır daha sonra integraller için trapez metodu kullanılır. Buradan elde edilen denklem sistemi Thomas algoritması ile çözülür. Önerilen yöntemin doğruluğunu ve ekonomikliğini ortaya koyan bir örnek sunulur.

Approximate Solution of Singularly Perturbed Problems with Numerical Integration Method

Öz

In this study, the numerical integration method is performed for approximate solution of the singularly perturbed Volterra integro-differential equations. Firstly, it starts with the finite difference method on the uniform mesh points, then the trapezoidal method is used for integrals. The system of equations obtained here is solved with the Thomas algorithm. An example is presented that demonstrates the accuracy and economy of the proposed method.
