TBA equations for $S U (r + 1)$ quantum Seiberg-Witten curve: higher-order Mathieu equation

Feiyu Peng, Hongfei Shu

We develop the ODE/IM correspondence for the higher-order Mathieu equation arising from the quantum Seiberg-Witten curve of the pure $S U (r + 1)$ $N = 2$ supersymmetric Yang-Mill…

Truncating Dyson-Schwinger Equations Based on Lefschetz Thimble Decomposition and Borel Resummation

Feiyu Peng, Hongfei Shu

We study the zero-dimensional prototype of the path integrals in quantum mechanics and quantum field theory, with the action $S (ϕ) = \frac{σ}{2} ϕ^{2} + \frac{λ}{4} ϕ^{4}$ . Using the Lefsc…
