The Sullivan-conjecture claims that complex projective
complete intersections are classified up to diffeomorphism by their
total degree, Euler-characteristic and Pontryagin-classes. It follows
from work of Kreck and Traving that the conjecture holds in complex
dimension 4 if the total degree is divisible by 16. In this talk I
will present the proof of the remaining cases. It is known that the
conjecture holds up to connected sum with the exotic 8-sphere (this is
a result of Fang and Klaus), so the essential part of our proof is
understanding the effect of this operation on complete intersections.
This is joint work with Diarmuid Crowley.
