Unlike other authors, we consider only spiral galaxies. In this paper, we present empirical formulas derived from observations of 54 spiral galaxies, establishing connections between the mass of the central black hole (MBH), the bulge stellar mass (Mbulge), and the velocity dispersion (σ) of stars in it. A non-linear non-stationary disk model with an anisotropic velocity diagram is constructed. Within this model, the instabilities of individual perturbation modes are studied. The increments of instability are calculated depending on the physical parameters of the model. These values are compared across three perturbation modes. The paper is partly based on the report presented at the conference “Modern Stellar Astronomy-2022,” held at the Caucasian Mountain Observatory of the Sternberg Astronomical Institute of Lomonosov Moscow State University, on November 8–10, 2022.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181325065008">С целью изучения влияния центральной черной дыры на формирование балджа спиральных галактик выполнен анализ связи между массами сверхмассивных черных дыр (СЧД) с параметрами их балджей. В отличие от других авторов, мы рассматриваем только спиральные галактики. В этой статье на основе данных наблюдений 54 спиральных галактик получены эмпирические формулы между массой центральной черной дыры (\({{M}_{{{\text{BH}}}}}\)) и звездной массой балджа (\({{M}_{{{\text{bulge}}}}}\)) и дисперсией скоростей (\(\sigma \)) звезд в нем. Построена нелинейно нестационарная модель диска с анизотропной диаграммой скоростей. На фоне этой модели изучены неустойчивости отдельных мод возмущений. Вычислены значения инкрементов неустойчивостей в зависимости от физических параметров модели. Выполнено их сравнение в рамках трех мод возмущений. Статья частично основана на докладе, представленном на конференции “Современная звездная астрономия-2022”, прошедшей в Кавказской горной обсерватории ГАИШ МГУ им. М.В. Ломоносова 8–10 ноября 2022 г.</p></trans-abstract><kwd-group xml:lang="en"><kwd>nonlinear model</kwd><kwd>non-stationary self-gravitating disk</kwd><kwd>bulge of the galaxy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нелинейная модель</kwd><kwd>нестационарный самогравитирующий диск</kwd><kwd>балдж Галактики</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>K.
