| | | | | In this previous posthere(from 2018), I described some ``back of the envelope calculations'' (based on private conversations with Scott Wolpert) indicating that some sectional curvatures of theWeil--Petersson (WP) metriccould be at least exponentially small in terms of the distance to the boundary divisor of Deligne--Mumford compactification. Very roughly speaking, this heuristic computation went as follows:... | |

| | | Consider a smooth one-parameter family $latex {f_t}$ of diffeomorphisms on a manifold $latex M$. It is a flow if $latex f_0(x)=x$ and $latex f_{t}\circ f_{s}(x) = f_{s+t}(x)$ for every $latex x\in M$, , $latex t ,s \in \mathbb{R}$. Set $latex X(x)=\lim\limits_{h\to 0} \frac{1}{h}(f_h(x) - x)$. This generates a vector field $latex X: M \to TM$.... | ||
