Aspherical products which do not support Anosov diffeomorphisms
Andrey Gogolev, Jean-François Lafont
We show that the product of infranilmanifolds with certain aspherical closed manifolds do not support Anosov diffeomorphisms. As a special case, we obtain that products of a nilman…
Combinatorial systolic inequalities
Ryan Kowalick, Jean-François Lafont, Barry Minemyer
We establish combinatorial versions of various classical systolic inequalities. For a smooth triangulation of a closed smooth manifold, the minimal number of edges in a homotopical…
Hyperbolic groups with boundary an n-dimensional Sierpinski space
Jean-François Lafont, Bena Tshishiku
For n>6, we show that if G is a torsion-free hyperbolic group whose visual boundary is an (n-2)-dimensional Sierpinski space, then G=π_1(W) for some aspherical n-manifold W with no…
Barycentric straightening and bounded cohomology
Jean-François Lafont, Shi Wang
We study the barycentric straightening of simplices in irreducible symmetric spaces of non-compact type. We show that, for an n-dimensional symmetric space of rank r>1, the p-Jacob…
Marked length rigidity for Fuchsian buildings
David Constantine, Jean-François Lafont
We consider finite 2-complexes X that arise as quotients of Fuchsian buildings by subgroups of the combinatorial automorphism group, which we assume act freely and cocompactly. We…
