Given the matrix $ A \in \mathbb{R}^{m\times n}$ of rank k, the problem is to find a matrix $ B \in \mathbb{R}^{m\times n}$ of rank c<k iteratively minimizing $ \left \| A – B_i \right \|_{F}$ If the sequence $ \left \| A – B_i \right \|_{F}$ is monotonically decreasing at every step, is itRead more

Let $ M$ be smooth compact riemannian manifold with boundary and $ \varphi_0: S^1\to M$ be a rectifiable curve (or a smooth one). I would like to find a reference to the following statement: Statement. There exists a length decreasing homotopy $ \varphi_t:S^1\to M$ , $ t\in [0,1]$ , such that the curve $ \varphi_1(S^1)$Read more
