The first-kind Volterra integral equations are a very important kind of integral equa-tions. It has been developed and matured since the twentieth century. Many practicalproblems about physics and mechanics can be solved by changing into the first-kindVolterra integral equations. When the kernel function is continuous or weakly singu-lar, the exact solution is always di?cult to work out. Therefore, the numerical methodsof the first-kind Volterra integral equations play a very important role in mathematics. Byresearching the first-kind Volterra integral equations, there are many wonderful analysis .This article considers the numerical methods of the first-kind Volterra integral equationswhen the data are undisturbed and disturbed.This structure is as follows:In chapterⅠ, we introduce the background , the domestic and foreign researchingsituation and the developping tendency of the first-kind Volterra integral equations. Thisarticle lists some classical methods of solving the first-kind Volterra integral equations.In chapterⅡ,we show some preparatory theory of solving the first-kind Volterraintegral equations, ill-posed problems, the regularization methods using in this article:Tikhonov regularization method,total variation regularization method .In chapterⅢ, we research the numerical methods of the first-kind Volterra integralequations when the data is undisturbed, The format structure and convergence analysisare also introduced in this article.In chapterⅣ, we give a numerical experiment based on Tikhonov regularizationmethod and total variation regularization method.The regularization parameter method isthe L-curve method. |
