Index Concepts for Differential-Algebraic Equations

open access: yes, 2015
We discuss several of different index concepts for differential-algebraic equation (differentiation, strangeness, tractability, geometric, perturbation, and structural index) and analyze their relationship.

Differential/Algebraic Equations As Stiff Ordinary Differential Equations

open access: yesSIAM Journal on Numerical Analysis, 1992
This paper deals with the relation between differential/algebraic equations (DAEs) and certain stiff ODEs and their respective discretizations by implicit Runge–Kutta methods. For that purpose for any DAE a singular perturbed ODE is constructed such that the DAE is its reduced problem and the solution of the ODE converges in some sense to that of the ...

Algebraic Theory of Differential Equations

open access: yes, 2008
Integration of differential equations is a central problem in mathematics and several approaches have been developed by studying analytic, algebraic, and algorithmic aspects of the subject. One of these is Differential Galois Theory, developed by Kolchin and his school, and another originates from the Soliton Theory and Inverse Spectral Transform ...
