Concavity Property of Minimal \(L^{2}\) Integrals with Lebesgue Measurable Gain VII–Negligible Weights

In this article, we present characterizations of the concavity property of minimal \(L^2\) integrals with negligible weights degenerating to linearity on the fibrations over open Riemann surfaces and the fibrations over products of open Riemann surfaces. As applications, we obtain characterizations of the holding of equality in optimal jets \(L^2\) extension problem with negligible weights on the fibrations over open Riemann surfaces and the fibrations over products of open Riemann surfaces.
