Possible homology of closed manifolds.
In this fun paper,
it is pointed out that
- homology is a very basic invariant, and
- closed manifolds are very basic objects
and so a very basic question is: what sequences of abelian groups are the homology groups of a closed simply connected manifold?
It isn’t very hard to realize any sequence of abelian groups up to the middle dimension, but that middle dimension is tricky (e.g., classify
-connected
-manifolds).
Anyway, I was wondering: is this realization question solvable for homology with coefficients in
or
?

don’t mean to go off topic, but is there any chance you’ll update forgetmenot for leopard or safari 3.1?
you’ve got a devoted following… i need my undo close tab back!
