Some Insight into Many Constituent Dynamics

A description of many constituent (particle) systems with fuzzy initial conditions is proposed with the help of the field language. In this language correlation functions are defined and equations for them are derived in the free Fock space. Additional conditions for their solutions are postulated. The closure problem for polynomial, rational, local and nonlocal interactions is considered with exploitation of left or right invertibility of used operators. Some general remarks concerning symmetry and multi-scale descriptions are given.
