Induced metric

This mathematics-related article is a stub.

You can help Wikipedia by expanding it.In mathematics and theoretical physics, the induced metric is the metric tensor defined on a submanifold that is induced from the metric tensor on a manifold into which the submanifold is embedded, through the pullback.

[1] It may be determined using the following formula (using the Einstein summation convention), which is the component form of the pullback operation:[2] Here
