Abstract

We suppose to carry out the complex analysis of GRB time and spectral behaivour. In particular, we plane to study behaivour of some invariance to event duration time profiles specific charakteristics in dependence of GRB spectral types. We suppose to analyse GRB time profiles fractal index distributions in dependense of its spectral index in Band model. Fractal index is sensitive to change of shape and indentness of event time profile. Many of experimrntal signals are fractals by their lasting, and fractal dimensions must be different for time profiles of events which caused by different physical processes. We suppose to separate new GRB types with different fractal indexes, spectral indexes and hardness of spectra. We assume that existense of new GRB typesallow scientists to associate GRB models with real events and understand gamma-rays emitted mechanisms. However, we think that separations criteries for different GRB groups must include not only fractal index, but spectral index and hardness too. It is very inportant to use data with high time and spectral resolution to develop separation criteries and it is very useful to use data which accompanied by observations in different energy bands (from all INTEGRAL detectors).
