Exact WKB analysis of ℂℙ1 holomorphic blocks

Abstract

Abstract We study holomorphic blocks in the three dimensional N $$ \mathcal{N} $$ = 2 gauge theory that describes the ℂℙ1 model. We apply exact WKB methods to analyze the line operator identities associated to the holomorphic blocks and derive the analytic continuation formulae of the blocks as the twisted mass and FI parameter are varied. The main technical result we utilize is the connection formula for the 1𝜙1 q-hypergeometric function. We show in detail how the q-Borel resummation methods reproduce the results obtained previously by using block-integral methods.
