Laurent Schwartz introduced the term “distribution” by analogy with a distribution of electrical charge, possibly including… ## [“the Yang-Mills equations are nonlinear, therefore there is little hope of finding a closed-form…](https://isomorphismes.tumblr.com/post/764411280257875968) _2024-10-15 · isomorphismes_ “the Yang-Mills equations are nonlinear, therefore there is little hope of finding a closed-form solution.” Such a statement seems plausible. Linear differential equations with constant coefficients are the only differential equations for which a general solution is given in closed form. As often occurs in life, however, the exceptions to the rule are sometimes more interesting than the rules… ## [Hadamard knew in 1898 that negative curvature and simply connectedness for surfaces embedded in…](https://isomorphismes.tumblr.com/post/764232859576893441) _2024-10-13 · isomorphismes_ Hadamard knew in 1898 that negative curvature and simply connectedness for surfaces embedded in 3-space force uniqueness of geodesics joining two points—implying that any segment of geodesic is also a shortest path. But there is a long way toward the modern statement: “on any complete abstract Riemannian manifold of ≥0 curvature of any dimension, curvature is the quotient of its universal covering…
