Borel resummation
WebJun 25, 2024 · To give an analytic meaning to WKB solutions, we employ the Borel resummation technique (or the Borel-Laplace method) with respect to a large parameter η in the exact WKB analysis. Definition 2.4 Let η > 0 be a large parameter. For an infinite series f = exp ( ηy 0) ∑ n ≥ 0 f n η − (n+α) ( α > 0, y 0, f n : constants), we define WebBorel summation is appropriate always when one can prove the analyticity assumption that the Borel integrals satisfy for complex g g ( Watson's Theorem ). This is the case for …

It is particularly useful for summing divergent … WebJul 8, 2024 · We argue that the perturbative series for the \overline {\mathrm {MS}} β -function is most likely asymptotic and non -Borel resummable, yet Borel resummation techniques allow to improve on ordinary perturbation theory. We find substantial evidence that QCD with nf = 12 flavours flows in the IR to a conformal field theory.
