Approximation of tensor fields on surfaces of arbitrary topology based on local Monge parametrizations
Alejandro Torres-Sánchez, Daniel Santos-Oliván, Marino Arroyo
We introduce a new method, the Local Monge Parametrizations (LMP) method, to approximate tensor fields on general surfaces given by a collection of local parametrizations, e.g.~as…

Numerical Relativity with Arbitrary Precision Arithmetic: Applications to Gravitational Collapse
Daniel Santos-Oliván, Carlos F. Sopuerta
Numerical Relativity is a mature field with many applications in Astrophysics, Cosmology and even in Fundamental Physics. As such, we are entering a stage in which new sophisticate…

Moving Closer to the Collapse of a Massless Scalar Field in Spherically Symmetric Anti-de Sitter Spacetimes
Daniel Santos-Oliván, Carlos F. Sopuerta
We present a new hybrid Cauchy-characteristic evolution method that is particularly suited for the study of gravitational collapse in spherically-symmetric asymptotically (global)…
