Abstract:
      Yu introduced Property A on discrete metric spaces. In this paper, a relative Property A for a discrete metric space $X$ with respect to a set $Y$ and a map $\rho_{X,Y}$ is defined. Some characterizations for relative Property A are given. In particular, a discrete metric space with relative Property A can be coarse embedding into a Hilbert space under certain condition.
