Higher-derivative gravitational effective field theories are generically weakly hyperbolic
Farid Thaalba, Fernando Abalos, Miguel Bezares
The paper studies the initial‑value problem for metric higher‑derivative gravitational effective field theories and demonstrates that any such theory with characteristic speeds ind…
Neutron star evolution with the Bemfica-Disconzi-Noronha-Kovtun viscous hydrodynamics framework
Harry L. H. Shum, Fernando Abalos, Yago Bea +3
The recently proposed first-order viscous relativistic hydrodynamics formulation by Bemfica, Disconzi, Noronha, and Kovtun (commonly known as the BDNK formulation) has been shown t…
A strongly hyperbolic viscous relativistic hydrodynamics theory with first-order charge current
Federico Schianchi, Fernando Abalos
We extend the first order dissipative relativistic hydrodynamics model of Bemfica-Disconzi-Noronha- Kovtun (BDNK) in order to include the charge number current in full first order…
Strong Hyperbolicity of Second-Order PDEs via Matrix Pencils
Fernando Abalos, David Hilditch
We introduce a definition of strong hyperbolicity for second order partial differential equations using second order pencils. We show that this definition is equivalent to the stan…
Hyperbolic extensions of constrained PDEs
Fernando Abalos, Oscar Reula, David Hilditch
Systems of PDEs comprised of a combination of constraints and evolution equations are ubiquitous in physics. For both theoretical and practical reasons, such as numerical integrati…
