Classification of the functions of several arguments could be reduced to the theory of degenrated random tensors (matrices for two arguments). This link is useful for both directions. In the special cases, for example classification of metric spaces with measures (Gromov mm-spaces) it is possible to study the space of all classes. A special role belongs to remarkable but completely forgotten universal Urysohn space.
