Linear differential algebraic equations of index 1 and their adjoint equations
For linear DAEs of tractability index 1 adjoint equation is introduced. The solvability of this adjoint equation is shown at the lowest possible smoothness. The fundamental matrices of both equations are defined and their relationships are characterized. The Lagrange identity for DAEs is introduced as an extension of the Lagrange identity that is well-known for ODEs. All analyses are made in great detail.
