This paper mainly discusses the stability of generalized Busemann-Petty problem, its results involve in the stability of generalized Busemann-Petty problem on dimension-restriction and the stability of Busemann-Petty problem related to generalized-intersection-like structure. The results in this paper more detailedly segments and contains the stability results of generalized Busemann-Petty problem given by Koldobsky and Ma Dan, providing the enlightenment for deepening the related researches.
