摘要：We introduce a new definition of nonpositive curvature in metric spaces and study its relationship to the existing notions of nonpositive curvature in comparison

 geometry. The main feature of our definition is that it applies to all metric spaces and does not rely on geodesics. It is believed to be of interest in geometric data analysis.
