Exotic spheres

1 Introduction

I should like to start this exotic spheres page by a link to my exotic spheres home page, which already has a large collection of original source material, which it would be inappropriate to put on the Manifold Atlas directly.
Andrew Ranicki

2 Construction and examples

[Milnor1956]

3 Invariants

Signature, Kervaire invaiant

4 Classification/Characterization (if available)

[Kervaire&Milnor1963]

5 Further discussion

... is welcome
