Degree of the divisor of solutions of a differential equation on a projective variety [PDF]

, 1999
Using the data schemes developed by Arrondo-Sols-Speiser, we give a rigorous definition of algebraic differential equations on the complex projective space $P^n$.

Level set methods for computing reachable sets of systems with differential algebraic equation dynamics

American Control Conference, 2008
Most existing algorithms for approximating the reachable sets of continuous systems assume an ordinary differential equation model of system evolution.

Ordinary differential equations described by their Lie symmetry algebra [PDF]

Published in J. Geom. Phys. 85 (2014), 2-15, 2014
The theory of Lie remarkable equations, i.e. differential equations characterized by their Lie point symmetries, is reviewed and applied to ordinary differential equations. In particular, we consider some relevant Lie algebras of vector fields on $\mathbb{R}^k$ and characterize Lie remarkable equations admitted by the considered Lie algebras.

On differential–algebraic equations in infinite dimensions [PDF]

Journal of Differential Equations, 2019
We consider a class of differential-algebraic equations (DAEs) with index zero in an infinite dimensional Hilbert space. We define a space of consistent initial values, which lead to classical continuously differential solutions for the associated DAE.
