Integral equations on the half-line with difference kernels and nonlinear functional equatons

N. B. Engibaryan, A. A. Arutyunyan


Abstract: In this paper we present a new approach to the solution of scalar and operator equations of the form
\begin{equation*} f(x)=g(x)+\int_0^\infty T(x-t)f(t)\,dt. \tag{A} \end{equation*}

We derive and study some new functional equations, occupying an intermediate position between the equation (A) and the Ambarcumyan equation. This approach leads to a very simple way of deriving and generalizing Ambarcumyan's equations.
