摘　　要：In this paper,we consider the intricate thermodynamic topology of quantum-corrected Anti-de Sitter-Reissner-Nordstrm(AdS-RN)black holes within the framework of Kiselev spacetime.By employing the generalized off-shell Helmholtz free energy approach,we meticulously compute the thermodynamic topology of these selected black holes.Furthermore,we establish their topological classifications.Our findings reveal that quantum correction terms influence the topological charges of black holes in Kiselev spacetime,leading to novel insights into topological classifications.Our research findings elucidate that,in contrast to the scenario in whichω=0 and a=0.7 with total topological charge W=0 andω=-4/3 with total topological charge W=-1,in other cases,the total topological charge for the black hole under consideration predominantly stabilizes at+1.This stabilization occurs with the significant influence of the parameters a,c,andωon the number of topological charges.Specifically,whenωassumes the values ofω=-1/3,ω=-2/3,andω=-1,the total topological charge will consistently be W=+1.
