La Liga has El Clásico, France has Le Classique, and Argentina goes full gun with its Superclásico. English football has no true equivalent, with Liverpool and Manchester United fans unable to agree on a name for their grand-slam meetings. Up in the land of fitba, there’s this weekend’s 450th Old Firm/Glasgow derby (delete as applicable according to your stringency on Scottish company law). And Germany has Der Klassiker, between Bayern Munich and Borussia Dortmund. The Bundesliga marketing suits have been out in force this week for the one game, played on Saturday evening, that brings extra eyeballs. Though questions are often raised over whether this is a true, classic rivalry; Dortmund have not won a league title since Jürgen Klopp was making his rounds in 2012.，推荐阅读谷歌浏览器【最新下载地址】获取更多信息

A Riemannian metric on a smooth manifold \(M\) is a family of inner products \[g_p : T_pM \times T_pM \;\longrightarrow\; \mathbb{R}, \qquad p \in M,\] varying smoothly in \(p\), such that each \(g_p\) is symmetric and positive-definite. In local coordinates the metric is completely determined by its values on basis tangent vectors: \[g_{ij}(p) \;:=\; g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\; \frac{\partial}{\partial x^j}\bigg|_p\right), \qquad g_{ij} = g_{ji},\] with the matrix \((g_{ij}(p))\) positive-definite at every point. The length of a tangent vector \(v = \sum_i v^i \frac{\partial}{\partial x^i}\in T_pM\) is then \(\|v\|_g = \sqrt{\sum_{i,j} g_{ij}(p)\, v^i v^j}\).
