| contents | In this article, we introduce a modification of the timelike Hausdorff measure VN defined by McCann and Samann on Lorentzian pre-length spaces. We write the modification of VN as WN. We establish volume comparison inequalities by causality preserving and timelike Lipschitz maps for VN and WN, and discuss basic properties of both VN and WN. Moreover, we show the coincidence of WN and VN on smooth spacetimes and some Lorentzian pre-length spaces, and construct some examples of timelike Lipschitz maps and causality preserving maps. |
