On Homology Classes Not Representable by Products
نویسنده
چکیده
We show that Preissmann’s theorem implies that no closed negatively curved manifold is dominated by a non-trivial product. We also show that a fiber bundle whose base and fiber are negatively curved is dominated by a product if and only if it has a finite covering space which is a trivial bundle.

We characterize integral homology classes of the product of two projective planes which are representable by a subvariety.
متن کاملFundamental Classes Not Representable by Products
We prove that rationally essential manifolds with suitably large fundamental groups do not admit any maps of non-zero degree from products of closed manifolds of positive dimension. Particular examples include all manifolds of non-positive sectional curvature of rank one and all irreducible locally symmetric spaces of non-compact type. For closed manifolds from certain classes, say non-positive...
متن کاملKleene Theorems for Labelled Free Choice Nets without product acceptance condition
In an earlier work [18], we provided expressions for free choice nets having “distributed choice property” which makes the nets “direct product” representable. In a recent work [17], we gave equivalent syntax for a larger class of free choice nets obtained by dropping “distributed choice property”, thus syntactically characterizing nets which are not representable by direct products also. In bo...
متن کاملOn the gap between representability and collapsibility
A simplicial complex K is called d-representable if it is the nerve of a collection of convex sets in R; K is d-collapsible if it can be reduced to an empty complex by repeatedly removing a face of dimension at most d − 1 that is contained in a unique maximal face; and K is d-Leray if every induced subcomplex of K has vanishing homology of dimension d and larger. It is known that d-representabl...
متن کاملFundamental Classes of Negatively Curved Manifolds Cannot Be Represented by Products of Manifolds
Not every singular homology class is the push-forward of the fundamental class of some manifold. In the same spirit, one can study the following problem: Which singular homology classes are the push-forward of the fundamental class of a given type of manifolds? In the present article, we show that the fundamental classes of negatively curved manifolds cannot be represented by a non-trivial prod...
