Singüler Pertürbe Özellikli Yarılineer Gecikmeli Diferansiyel Denklemlerin Nümerik Çözümleri

Bu çalışmada sabit gecikme içeren singüler pertürbe özellikli kuasilineer diferansiyel denklemlerin nümerik çözümleri araştırılmıştır. Lineer baz fonksiyonları ve interpolasyon kuadratür kurallarını kullanarak Boglaev-Bakhvalov tipli şebeke üzerinde sonlu fark şeması kurulmuştur. Ayrık maksimum normda hata yaklaşımları elde edilmiştir. Teorik analizi doğrulamak için bir adet nümerik örnek çözülmüştür.

Numerical Solutions of the Singularly Perturbed Semilinear Delay Differential Equations

In this study, the numerical solution of the singularly perturbed quasilinear differential equations with constant delay is investigated by the method of integral identities with use of linear basis functions and interpolating quadrature formulas, a finite difference scheme is established on Boglaev-Bakhvalov type mesh. The error approximations are obtained in the discrete maximum norm. A numerical example is solved to clarify the theoretical analysis.
