Semi-explicit DAE of Index 1
DAE of the form
are called semi-explicit. The index-1 property requires that g is solvable for y. In other words, the differentiation index is 1 if by differentiation of the algebraic equations for t an implicit ODE system results,
which is solvable for if
Every sufficiently smooth DAE is almost everywhere reducible to this semi-explicit index-1 form.

“Exile as a mode of genius no longer exists; in place of Joyce we have the fragments of work appearing in Index on Censorship.”
