AbstractWe introduce the definition of Borel resummation and its applications in differential equations and difference equations, e.g., Airy, dilogarithm..
AbstractThe torus partition function of TTbar-deformed CFTs is modular invariant. Using this fact, it is shown that TTbar-deformed CFTs exhibit a universal free energy in the high temperature limit and a universal spectrum in the high energy limit. In this work, we show that a much stronger form of universality holds in TTbar-deformed CFTs with a large central charge c for both the double and s...
