Smoothness of standard maps associated to the product of manifolds #
This file contains results about smoothness of standard maps associated to products of manifolds
- if
f
andg
are smooth, so is their point-wise product. - the component projections from a product of manifolds are smooth.
- functions into a product (pi type) are smooth iff their components are
