Report

Perturbatively conserved higher nonlocal charges of free-surface deep-water gravity waves

Autor: Neveu, André

We exhibit a set of six explicit higher nonlocal charges of free-surface deep-water gravity waves conserved in lowest nontrivial orders of perturbation in the amplitude of the surface displacement.

Chiral Condensate and Spectral Density at full five-loop and partial six-loop orders of Renormalization Group Optimized Perturbation

Autor: Kneur, Jean-Loic, Neveu, André

Publikováno v: Phys. Rev. D 101, 074009 (2020)

We reconsider our former determination of the chiral quark condensate $\langle \bar q q \rangle$ from the related QCD spectral density of the Euclidean Dirac operator, using our Renormalization Group Optimized Perturbation (RGOPT) approach. Thanks to

A B\'acklund transformation for elliptic four-point conformal blocks

Autor: Neveu, André

We apply an integral transformation to solutions of a partial differential equation for five-point correlation functions in Liouville theory on a sphere with one degenerate field $V_{-\frac{1}{2b}}$. By repeating this transformation, we can reach a w
