Abstract:

The main purpose of this work is to solve the Volterra integral equation of the first kind with noise data by using both a Legendre-collocation method and a regularization strategy. We provide a rigorous convergence analysis for the proposed method. Some numerical tests are illustrated to demonstrate the validity and effectiveness of the proposed method.

Key words: Spectral method, Regularization strategy, Volterra integral equation, Convergence analysis
