An Existence Theorem for a Nonlinear Integral Equation of Urysohn Type in $\Boldsymbol{l^p(\mathbb{r}^n)}$

On the solvability of a functional Volterra integral equation

“…Integral equations play an important role in the theory of nonlinear analysis and its applications in mathematical physics, biology, engineering, economics, radiation transfer theory and mechanics (see [7], [8], [11], [12], [26]). For a review of various integral equations and their applications, see ( [1], [3], [10], [13], [15], [19], [21], [22]).…”
