In mathematics, the metric derivative is a notion of derivative appropriate to parametrized paths in metric spaces. It generalizes the notion of "speed"...

covariant derivative could be defined abstractly without the presence of a metric. The crucial feature was not a particular dependence on the metric, but that...

covariant derivative is the Levi-Civita connection of a certain metric, then the geodesics for the connection are precisely those geodesics of the metric that...

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held...

Metric is a Canadian indie rock band founded in 1998 in Toronto, Ontario. The band consists of Emily Haines (lead vocals, synthesizers, guitar, tambourine...

Riemann, who first conceptualized them. Formally, a Riemannian metric (or just a metric) on a smooth manifold is a choice of inner product for each tangent...

nonmetricity tensor in differential geometry is the covariant derivative of the metric tensor. It is therefore a tensor field of order three. It vanishes...

At this point the metric cannot be extended in a smooth manner (the Kretschmann invariant involves second derivatives of the metric), spacetime itself...

every function that is defined on an interval and has a bounded first derivative is Lipschitz continuous. In the theory of differential equations, Lipschitz...
