In this paper, we study smooth metric measure space (M, g, e (-f) dv) satisfying a weighted Poincar, inequality and establish a rigidity theorem for such a space under a suitable Bakry-A parts per thousand mery curvature lower bound. We also consider the space of f-harmonic functions with finite energy and prove a structure theorem.
