Abstract
In this paper we discuss the most recent results concerning the Vlasov dynamics inside the spinodal region. The chaotic behavior which follo ws an initial regular evolution is characterized through the calculati on of the fractal dimension of the distribution of the final modes exc ited. The ambiguous role of the largest Lyapunov exponent for unstable systems is also critically reviewed. This investigation seems to conf irm the crucial role played by deterministic chaos in nuclear multifra gmentation.
