Numerical stability of the Hyperbolic Formulation of the Constraint equations for ${\mathbb{T}}^3$ cosmological space-times

Alejandro Estrada-Llesta, Cristhian Martinez-Duarte, Leon Escobar-Diaz

In this work, we study of the algebraic-hyperbolic formulation of the Einstein constraint equations for numerically constructing initial data sets for inhomogeneous cosmological sp…
