| | | | | Following on from last post I want to talk about the appropriate notion of morphism between the objects I defined. Recall that these are Lie groupoids $latex X$ with a map to the manifold $latex M$ satisfying some properties ($latex X_0 \to M$ and $latex X_1 \to X_0\times_MX_0$ are surjective submersions), and then equipped with... | |

| | | The ``probabilistic method'' is the art of applying probabilistic thinking to non-probabilistic problems. Applications of the probabilistic method often feel like magic. Here is my favorite example: Theorem (Erdös, 1965). Call a set $latex {X}&fg=000000$ sum-free if for all $latex {a, b \in X}&fg=000000$, we have $latex {a + b \not\in X}&fg=000000$. For any finite... | ||
