Classify of Stiefel-Whitney
In Geometry, the classes of Stiefel-Whitney are classes characteristic associated with the vectorial real fibers of finished row.
They thus constitute a real analog of the classes of Chern in the complex case.
It bear the name of Hassler Whitney and Eduard Stiefel.
Any characteristic class associated with fibers vectorial realities seems a polynomial in the classes of Stiefel-Withney.
