Abstract
For time-varying semilinear differential-algebraic equations, we prove theorems on the existence and uniqueness of global solutions and theorems on Lagrange stability (boundedness of global solutions), dissipativity (ultimate boundedness of solutions), and Lagrange instability (absence of global solutions).
