Gradient flows of $(K,N)$-convex functions with negative $N$

Lorenzo Dello Schiavo, Mattia Magnabosco, Chiara Rigoni

We discuss $(K,N)$-convexity and gradient flows for $(K,N)$-convex functionals on metric spaces, in the case of real $K$ and negative $N$. In this generality, it is necessary to co…
