DESCRIPTION:Speakers: Tatiana Dedovich (Joint Institute for Nuclear Resear
 ch)\nResults of fractal analysis of Au+Au events at the energy of $\\sqrt{
 s_{NN}} = 200$ GeV/c by the method of the equation systems of power coveri
 ngs (SePaC) [1] are presented. A Multi-Phase Transport (AMPT) model [2\,3]
  to generate events in relativistic heavy ion collisions was used. In Even
 t-by-Event analysis a distribution on the transverse momentum $p_Т$ of ne
 gatively charged particles produced in the pseudo-rapidity interval $|\\et
 a| <0.5$ in the events with different centrality from 0-5% to 30-40% was s
 tudied.\nThe fractal data set includes 1823 events obtained by independent
  [4]\, dependent [5]\, and combined [6] partition. Fractal events differ i
 n multiplicity (from 8 to 1024)\, the base of formation $P_F$ (from 3 to 8
 )\, and the type of structures. The criteria characterizing the similarity
  of structures at different levels and reducing the portion of background 
 events (mixed data\, events with Gaussian\, exponential\, and uniform dist
 ributions) [7] were used. \nComparison of the Monte Carlo fractals\, rando
 m events and AMPT events was performed. It was found that the multiplicity
  distribution for the sets of random events coincides with the distributio
 n obtained using the AMPT generator. Distribution of fractal events with d
 ifferent multiplicity on the dimension DF was obtained and their structure
  is discussed. The results of applying the selection criteria for various 
 types of events are presented.\n\n1. T. G. Dedovich\, M.V. Tokarev\, Phys.
