DESCRIPTION:The Sullivan-conjecture claims that complex projec
tive complete intersections are classified up to d
iffeomorphism by their total degree\, Euler-charac
teristic and Pontryagin-classes. Kreck and Traving
showed that the conjecture holds in complex dimen
sion 4 if the total degree is divisible by 16. In
this talk I will present the proof of the remainin
g 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 pa
rt of our proof is understanding the effect of thi
s operation on complete intersections. This is joi
nt work with Diarmuid Crowley.
