Abstract:
A method is suggested for the mathematical description of the asymmetry
occurring in the radio-source structures. The method is based on the
transformation of the radio structure into 'itself' and may be used for all
morphological types of structures. Two models of generation of the source
asymmetry are investigated, namely Doppler effects and the flip-flop
mechanism, with an assumption that the luminosity of the plasma volume
depends on time as a power law S approximately t(exp mu). The model with
Doppler effects turns out to be more suitable than that with flip-flop
mechanism.
