“…Additionally, the insertion of a point charge, also known as the Christoffel perturbation has a physical application for instance, in the context of the massive quantum field theory [3,6]. Let us also mention that the insertion of a point charge has been extensively studied in the context of planar (skew-)orthogonal polynomials, see, e.g., [6,14,53] and references therein. On the one hand, the local statistics of the ensemble also depends on the local geometry of the droplet.…”
