✦ Synopsis

We give an explicit criterion for when a pulse will first contract before eventually spreading. The contraction time is explicitly given and it is shown that the important quantity is the initial correlation between position and group velocity. A simple physical model is presented that explains why sometimes pulses contract before eventually expanding.

Hankel partial contraction is a Hankel matrix such that not all of its entries are determined, but in which every well-defined submatrix is a contraction. We address the problem of whether a Hankel partial contraction in which the upper left triangle is known can be completed to a contraction. It is

clear that, when applied to this slab problem, the three-stage CGFFT also suffers from divergence, as accuracy is required beyond 0.5 \* lo-', in a similar way to its application to the dielectric sphere in Figure 1. Again, there is no such breakdown with the three-stage versions of the MST and GNS,
