Distributional asymptotic expansions of spectral functions and of the associated Green kernels.
We define an integral, the distributional integral of functions of one real variable, that is more general than the Lebesgue and the Denjoy-Perron-Henstock-Kurzweil integrals, and which allows the integration of functions with distributional values everywhere or nearly everywhere. Our integral has the property that if f is locally distributionally integrable over the real line and ψ ∈ (ℝ) is a test function, then fψ is distributionally integrable, and the formula , defines a distribution ∈ ’(ℝ)...
