# 3 Linear DAEs with Constant Coefficients

# Basic Definitions and Notions

- variable transforms and scalings do not affect solvability
- DAEs <-> (E, A) matrix pairs
- canonical forms – Kronecker canonical form – canonical form of a linear DAE with constant coefficients
- Regularity and Solvability
- Weierstrass canonical form
