Non-Abelian and Type-A Conformal Anomalies from Euler Descent
Gleb Aminov, Csaba Csáki, Ofri Telem +1
We classify the non-Abelian anomaly of the Euclidean conformal group in dimensions via Stora-Zumino descent from its Euler invariant polynomial in dimensio…

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…
