. At present, the russian-language tutorial page is already available. Soon, we will place here materials on investigating collective effects in lattices of chaotic 1-D maps. The materials include a detailed description, references, MATLAB programs, and simulation results for lattices of various (1-D, 2-D, 3-D) dimensions.

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
