Basics of Multiple Polyexponential Integrals

Gleb Aminov, Paolo Arnaudo

We introduce a set of special functions called multiple polyexponential integrals, defined as iterated integrals of the exponential integral . These functions arise i…

Black hole scattering amplitudes via analytic small-frequency expansion and monodromy

Gleb Aminov, Paolo Arnaudo

We utilize three complementary approaches to pinpoint the exact form of scattering amplitudes in Schwarzschild spacetime. First, we solve the Regge-Wheeler equation perturbatively…
