dc.description.abstract In this thesis we studied the finite difference approximation for the solution of one dimensional parabolic inverse problem of finding the function ( ) and the unknown positive coeffient ( ) . The Backward time centered space (BTCS) which is unconditionally stable is studied and it’s convergent is proved using application of discrete maximum principle. Error estimates for ( ) and ( ) is studied and to give clear overview of the methodology several model problems are solved numerically. According to the experimental numerical results the concluding remark are presented. Keywords: finite difference methods, parabolic inverse problem, convergence, Error estimates, maximum principle. en_US
dc.description.abstract ÖZ : Bu tez tek boyutlu parabolik ters problemlerinin sayısal analiz tekniği kullanılarak çözülmesi ile ilgilidir. Çözüm esnasında klasik geri zaman merkezli sonlu farklar tekniği kullanılarak ( ) fonksiyonu ve yayılma katsayısı ( ) hesplanmıştır. Kullanılan sonlu farklar tekniğinin yakınsaması ayrık maksimum prensibi ile hesplanmış ayrıca ( ) ve ( ) bilinmeyenlerinin hata tahminleri çalışılmıştır. Sayısal analiz hesaplarında iki farklı denklem üzerinde çalışılmış ve sonuçlar ile düşünceler yazılmıştır. Anahtar kelimeler: sonlu fark yöntemleri, parabolik ters problemi sorun, yakınsama, hata tahminleri, maksimum ilkesi. en_US
