DESCRIPTION:Title:Exact WKB framework for quantum resonance and spectral t
 heoryAbstract:An attempt is made to unify the understanding of resonance p
 henomena\, analytic spectra\, and resurgence by developing and applying a 
 mature exact-WKB framework. We begin by formulating non-perturbative reson
 ances in quantum mechanics via the exact WKB method\, demonstrated concret
 ely in the inverted Rosen–Morse potential\, where barrier resonances and
  quasi-stationary states are shown to match exact and WKB predictions. Nex
 t\, we extend this framework to incorporate Zel’dovich regularization\, 
 complex scaling\, and a modified rigged Hilbert space\, thereby clarifying
  the equivalence and complementarity of these regularization methods and t
 he functional analytic structure they define. Finally\, we apply exact WKB
  and complex scaling to scattering problems\, compute the continuum spectr
 um and the S-matrix\, and reinterpret classical theorems such as Aguilar-B
 alslev-Combes and the Siegert boundary condition in this unified setting. 
 The result is a coherent picture in which resonant poles\, continuum spect
 ra\, and resurgent structures are seamlessly interconnected\, giving new i
 nsight into the spectral theory of unstable quantum states.
