Equipped with the
L2,q-distortion distance 𝚫
2,q, the space 𝕏
2,q of all metric measure spaces (
X, d, 𝔪) is proven to have nonnegative curvature in the sense of Alexandrov. Geodesics and tangent spaces are characterized in detail. Moreover, classes of semiconvex functionals and their gradient flows on 𝕏
2,q are presented.
