Summary: Theoretical and numerical investigations of the structure and dynamics of multiparticle systems of high multiplicity produced in hadron and nuclear collisions with particular emphasis on : a) dynamical fluctuations and manyparticle correlations, b) properties of particle distributions , c) the role of quantum statistics and the laws of conservation of quantum numbers on manyparticle correlation functions , d) the appearance of fractal structures in the process of aggregation of particles and e) nonlinear quantum optics and quantum algebras.

Keywords: multiparticle production, multiparticle dynamics, dynamical fluctuations, particle distributions, correlations, fractal structure, quantum statistics, nonlinear dynamics, quantum optics, quantum algebras.

Research goals: The aims of the proposed research program are theorerical and numerical investigations of: a) nonlinear dynamics of basic processes in hadron physics as well as in particle physics which are characterized by large dynamical fluctuations / chaoticity and/or fractality in physical observables (such as hadron multiplicity, transverse momentum, isospin, spin, charge and so on). b) properties of particle-distributions in the small regions of the phase space in connection with intermittency phenomena and fractality, c) relationship between manyparticle correlation functions and quantum statistics, scaling and fractal dimensions, d) the possibility of relating quantum algebras to the nonlinear character of the basic dynamical equations. It is expected to gain a better understanding of dynamical fluctuations, fractality and chaoticity in dynamical systems. The analysis of fractal dimensions can help to find the regions of strong dissipation of energy during formation and breakup of clusters of particles. Applications of quantum algebras to problems of nonlinear dynamics makes possible to gain better insight into the very structure of nonlinear processes.
