Smooth and topological Normal Invariants of complex projective 2-space
I calculate the group of normal invariants of complex projective 2-space and use it to classify fake complex projective 3-spaces.

Homotopy 7-spheres
I use the classification of fake complex projective 3-spaces to calculate which of the 28 homotopy 7-spheres arises as an S^1-bundle over a fake complex projective 3-space.
