Quaternionic line bundles over quaternionic projective spaces

2006
The authors consider the problem of enumerating the quaternionic line bundles over quaternionic projective spaces, that is, enumerating the set of based homotopy classes of self-maps of such projective spaces. They solve the problem completely in dimensions 2 and 3, and go a long way in the general case, where the answer depends only on the parity of ...
