On a problem of Hopf for circle bundles over aspherical manifolds with hyperbolic fundamental groups
Christoforos Neofytidis
We prove that a circle bundle over a closed oriented aspherical manifold with hyperbolic fundamental group admits a self-map of absolute degree greater than one if and only if it i…
Sets of degrees of maps between SU(2)-bundles over the 5-sphere
Jean-François Lafont, Christoforos Neofytidis
We compute the sets of degrees of maps between principal -bundles over , i.e. between any of the manifolds and . We show that the Steenrod squa…
Anosov diffeomorphisms of products I. Negative curvature and rational homology spheres
Christoforos Neofytidis
We show that various classes of products of manifolds do not support transitive Anosov diffeomorphisms. Exploiting the Ruelle-Sullivan cohomology class, we prove that the product o…
Domination between different products and finiteness of associated semi-norms
Christoforos Neofytidis
In this note we determine all possible dominations between different products of manifolds, when none of the factors of the codomain is dominated by products. As a consequence, we…
Invariant incompressible surfaces in reducible 3-manifolds
Christoforos Neofytidis, Shicheng Wang
We study the effect of the mapping class group of a reducible 3-manifold on each incompressible surface that is invariant under a self-homeomorphism of . As an application o…
