摘　　要：In this paper,we explore the quasinormal modes(QNMs)of a black hole surrounded by a fluid of strings within the framework of Rastall gravity.We analyze the behavior of scalar,electromagnetic,and gravitational perturbations,focusing on the influences of black hole charge Q and angular momentum l on the quasinormal frequencies.Our numerical results reveal a significant dependence on parameterε.These trends are consistent across different types of perturbations,emphasizing the relationship between black hole parameters and QNM behavior.
