Abstract: In this paper, a numerical method based on the Legendre spectrum configuration format is proposed to solve the third-kind Volterra integral differential equations with proportional delay terms. Firstly, the regularity of the equation solution is effectively improved by smooth transformation. Subsequently, using the interpolation property, the error analysis is given by theorem and lemma. Finally, numerical experiments are carried out to verify the effectiveness of the scheme and algorithm.
