Аннотация: The results on the properties of the stellar population of the central parts in nearby lenticular galaxies which are obtained with the Multi-Pupil Fibre field Spectrograph of the 6m telescope during the last 10 years are reported. Most S0 galaxies show prominent signs of nuclear star formation bursts some 3-5 Gyears ago; the unresolved nuclei are on average much younger than the surrounding bulges. Also I found that there is a link between the mean luminosity-weighted stellar population ages and the galaxy environment; in dense environments the stellar populations are older on average, both in the nuclei and in the bulges.
