Push forward mapping

WebThe information contained in the push-forward map is exactly what does my function do to tangent vectors. Pullbacks, acting on differentials of functions, act by taking the total derivative of a function. This works in a coordinate invariant way, and works without the notion of a metric. WebMay 21, 2015 · If you want to pull back a tangent vector from to , then you just use the inverse map to do a push-forward. The push-forward of a cotangent vector is defined similarly. So you guessed it right. When you want to go in the opposite of the normal direction, the map you're using needs to be invertible. bronxman said:

WebThe name makes sense, since we think of as "pulling back" the function f from N to M.. We can pull functions back, but we cannot push them forward. If we have a function g: M, there is no way we can compose g with to create a function on N; the arrows don't fit together correctly.But recall that a vector can be thought of as a derivative operator that maps … Web4.3A Mapping Currents.
