B. Jumarhon et M. Pidcock, REFORMULATION OF VOLTERRA INTEGRAL (INTEGRODIFFERENTIAL) EQUATIONS, Zeitschrift fur angewandte Mathematik und Mechanik, 76, 1996, pp. 565-566
In this paper, we show that by reformulating Volterra integral (or int
egro-differential) equations using the asymptotic expansions of the no
nsmooth solutions near the origin, some well-known product integration
methods can be employed to yield optimal convergence.
