Abstract
Results of extensive computer simulations performed in liquid water ar e reported in order to clarify the main features of dynamical density correlations in this system. Puzzling aspects, such as the anomalous s ound wave propagation at finite wave vectors, are related to the pecul iar structural aspects of this hydrogen-bonded liquid. Additional feat ures (such as the evolution of the relevant memory functions at increa sing wave vectors and the emergence of a second mode in the longitudin al current spectra) are also discussed in some detail.
