Based on the γ-ray Burst Monitor data of the Fermi space observatory, the light curve time structure of the γ-ray burst GRB 190114C in the energy range from 5 keV to 50 MeV was investigated. It was found that the temporal structure of the emission of this γ-ray burst contains quasi-periodic components with periods of 0.768 s, 1.28 s, 2.24 s, and 3.84 s, determined with an accuracy of up to ±0.064 s where the original data time bin is 0.064 s. We also analyzed the evolution of these quasi-period values during the background radiation intensity, which was recorded within 137 s before and within 354 s after the event. As a result, a systematic decrease with time in the value of the quasi-period of 3.84 s was found, while the value of the quasi-period of 0.768 s at the same time gradually increases. A similar unambiguous result for the quasi-periods of 1.28 s and 2.24 s was not obtained. According to the above estimates, it should be noted that the γ-ray burst itself is located within the time interval when oscillations with quasi-periods of 2.24 s and 3.84 s are in a multiple ratio of ~3/5. Such coincidence can serve as an indication of the significant role of resonance phenomena in the process of formation and flow of a γ-ray burst.
