TL;DR: In this article, the meson radiative decays were calculated under SU(3) covariance for a vector field inspired from local duality for the current propagator, and a new vector meson mass formula was also obtained leading to exactly ideal mixing.

TL;DR: In this paper, a further improvement on the convergence rate of Extrapolated Alternating Direction Implicit (EDI) schemes is described, where the first boundary value problem for Laplace's equation over the unit square is considered.
Abstract: This paper describes how a further improvement on the convergence rates of Extrapolated Alternating Direction Implicit schemes is possible. In the case of the first boundary value problem for Laplace's equation over the unit square an analysis is presented which can be extended to cover more general problems. In addition numerical examples which prove the validity of the analysis are given.

TL;DR: In this article, the renormalized finite-temperature σ-propagator for the Gross-Neveu model is constructed in the large -N limit, and the singularity structure of this Green function is used to analyze the finite-time vacuum excitations.
