Abstract: (Oxford University Press)
A non-perturbative effect in Îş (renormalized string coupling) obtained from the large order behavior in the vicinity of the prototypical Argyres–Douglas critical point of su(2), = 2, |N=2\mathcal {N} =2| supersymmetric gauge theory can be studied in the Gross–Witten–Wadia unitary matrix model with the log term: one as the work done against the barrier of the effective potential by a single eigenvalue lifted from the sea and the other as a non-perturbative function contained in the solutions of the nonlinear differential PainlevĂŠ II equation that goes beyond the asymptotic series. The leading behaviors are of the form |exp⁥{[−(4/3)(1/Îş)] [1,(s/K)3/2]}\exp \{[-({4}/{3})({1}/{\kappa })] \, [1, \left({s}/{K}\right)^{{3}/{2}}]\}|⁠. We make comments on their agreement.
