On the Convolution Equation with Positive Kernel Expressed via an Alternating Measure
B. N. Enginbarian Institute of Mathematics, National Academy of Sciences of Armenia
Abstract:
We consider the integral convolution equation on the half-line or on a finite interval with kernel
$$
K(x-t)=\int_a^be^{-|x-t|s}\,d\sigma(s)
$$
with an alternating measure $d\sigma$ under the conditions
$$
K(x)>0, \quad
\int_a^b\frac{1}{s}\,|d\sigma(s)|<+\infty, \quad
\int_{-\infty}^\infty K(x)\,dx=2\int_a^b\frac{1}{s}\,d\sigma(s)\le1.
$$
The solution of the nonlinear Ambartsumyan equation
$$
\varphi(s)=1+\varphi(s)\int_a^b\frac{\varphi(p)}{s+p}\,d\sigma(p),
$$
is constructed; it can be effectively used for solving the original convolution equation.
Keywords:
integral convolution equation, nonlinear Ambartsumyan equation, alternating measure, Wiener–Hopf operator, nonlinear factorization equation, Volterra equation.
