This paper deals with the study of the initial-boundary value problem of edge-hyperbolic system with damping 6 term on the manifold with edge singularity. More precisely, it is analyzed the invariance and vacuum isolating of the 7 solution sets to the edge-hyperbolic systems on edge Sobolev spaces. Then, by using a family of modi ed potential wells 8 and concavity methods, it is obtained existence and non-existence results of global solutions with exponential decay and 9 is shown the blow-up in nite time of solutions on the manifold with edge singularities.
