On a weakly singular Volterra integral equation

CALCOLO, 1981
The need for providing reliable numerical methods for the solution of weakly singular Volterra integral equations of first kind stems from the fact that they are connected to important problems in the theory and applications of stochastic processes. In the first section the above problems and some peculiarities of such equations are briefly sketched ...

Singular perturbation analysis of a certain volterra integral equation

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1972
An investigation is made of the asymptotic behavior of the solutionu(t;e) to the Volterra integral equation $$\varepsilon u(t;\varepsilon ) = \pi ^{ - \tfrac{1}{2}} \int\limits_0^t {(t - s)^{ - \tfrac{1}{2}} [f(s) - u^n (s;\varepsilon )]} ds, t \geqslant 0, n \geqslant 1$
