Volume forms can also be pulled back under covering maps, in which case they multiply volume by the cardinality of the fiber ( formally, by integration along the fiber ).
However, it also has a covariant map on cohomology, corresponding in de Rham cohomology to " integration along the fiber ", and a contravariant map on homology, corresponding in de Rham cohomology to " pointwise product with the fiber ".
It's difficult to find integration along the fiber in a sentence. 用integration along the fiber造句挺难的
