• Hyperbolic equations
• Well-posedness

In this note we show how to include low order terms in the C-infinity well-posedness results for weakly hyperbolic equations with analytic time-dependent coefficients. This is achieved by doing a different reduction to a system from the previously used one. We find the Levi conditions such that the C-infinity well-posedness continues to hold.
