(mathematics)
A tangent bundle TX over a differentiable manifold X is a Whitney sum of continuous bundles A and B over X if for each x the fibers of A and B at x are complementary subspaces of the tangent space at x.

We will thus need a good understanding of how this algebra behaves with respect to the Whitney sum and restriction to fixed points.
Let [mu]: BU x BU [right arrow] BU be the H-structure map which induces the Whitney sum on complex bundles.
to the usual Chern class, we have basically to check that the construction of the Whitney sum behaves well with respect to the [H.
