Discrete Laplacian structure and kernel reduction of the gap equation in odd-dimensional large-N vector models at imaginary chemical potential

We identify a mathematical structure in the gap equations of the large-N Gross–Neveu model at imaginary chemical potential in odd spacetime dimensions. Using this model as the primary example, the central observation is an elementary dimensional ladder: a single centred first difference with respect to σ2\documentclass...
