Sharp Energy Estimates for a Class of Weakly Hyperbolic Operators,ic operators with finite time degeneracy at time . = 0. Then, in a second part, we show that these energy estimates are sharp for a wide range of examples. In particular, for these examples we precisely determine the loss of regularity that occurs in passing from the Cauchy data at . = 0 to the solutions.
