Nonperturbative phenomena in field theory and gravity, and use of Borel summation to capture nonperturbative information

Rahman, Md Ashiq (BRAC University, 2017-12)

This thesis addresses non-perturbative phenomena and techniques to analyze nonperturbative problems. First, we discuss the simplest non-perturbative example in quantum gravity: blackholes, and how they non-perturbatively ...
