Sparse Discovery of Functional Relationships in Solutions to Systems of Differential Equations
Nicolae Tarfulea
This work develops a framework to discover relations between the components of the solution to a given initial-value problem for a first-order system of ordinary differential equat…

Observability for Initial Value Problems with Sparse Initial Data
Nicolae Tarfulea
In this work we introduce the concept of -sparse observability for large systems of ordinary differential equations. Let be such a system. At time , suppose…

Constraint Preserving Boundary Conditions for Hyperbolic Formulations of Einstein's Equations
Nicolae Tarfulea
Einstein's system of equations in the ADM decomposition involves two subsystems of equations: evolution equations and constraint equations. For numerical relativity, one typically…
