Mathematica、Matlab,这些都做到了。有些概念实际上是 Yann 和 Leon Bottou 通过他们在 Lush 和之前的工作中开创的,你实际上在任何其他科学框架中都看不到这些。张量别名、视图的概念实际上是 Yann 和 Leon 通过他们在 Lush 和之前的工作中开创的。实际上就是把你的 n 维数组看作是系统上非常接近逻辑内存的东西...

Let Σ be an orientable smooth hypersurface immersed on (M,g,f), the weighted weak index of a compact domain S of Σ, f−Indw(S), is the maximal dimension of the space W⊂{u∈C∞(S):∫Sue−fdS=0}, such that Q is negative-definite on W. The weighted weak index of Σ,...

In order to do so, we employ the theory of curves of maximal slope in slightly smaller spaces compactly embedding into the respective energy spaces associated to these functionals and add a term involving the logarithmic strain, which controls the parametrisations of the flowing (knotted) loops....
