摘　　要：For a Lorentzian invariant theory,the entanglement entropy should be a function of the domain of dependence of the subregion under consideration.More precisely,it should be a function of the domain of dependence and the appropriate cut-off.In this study,we refine the concept of cut-off to make it applicable to timelike regions and assume that the usual entanglement entropy formula also applies to timelike intervals.Using the Rindler method,the timelike entanglement entropy can be regarded as the thermal entropy of the CFT after the Rindler transformation plus a constant,where c denotes the central charge.The gravitational dual of the‘covariant'timelike entanglement entropy is presented following this method.
