Boundary conditions for axionic wormholes, imaginary distance bound and KSW allowability

Shubhashis Mallik, Neha, Gaurav Narain

We study four-dimensional axion wormholes in the Lorentzian mini-superspace path integral using dual scalar and three-form flux formulations. We analyze this duality for generic me…
