Wiener-Hopf equation: Kernels representable as a superposition of complex-valued exponents
The authors prove the unique solvability of the Wiener-Hopf integral equation \[ f(x)=g(x)+\int_0^\infty K(x-t)f(t)\,dt, \] where \(K(x)=\int_a^b e^{-| x| \lambda p}\, d\sigma(p)\) for a nondecreasing function \(\sigma\).
