Strongly scale-invariant virtually polycyclic groups
Jonas Deré
A finitely generated group is called strongly scale-invariant if there exists an injective endomorphism with the image of finite index in and the subgrou…
On closed manifolds admitting an Anosov diffeomorphism but no expanding map
Jonas Deré, Thomas Witdouck
A few years ago, the first example of a closed manifold admitting an Anosov diffeomorphism but no expanding map was given. Unfortunately, this example is not explicit and is high-d…
Anosov diffeomorphisms on infra-nilmanifolds associated to graphs
Jonas Deré, Meera Mainkar
Anosov diffeomorphisms on closed Riemannian manifolds are a type of dynamical systems exhibiting uniform hyperbolic behavior. Therefore their properties are intensively studied, in…
Orthogonal bi-invariant complex structures on metric Lie algebras
Jonas Deré
This paper studies how many orthogonal bi-invariant complex structures exist on a metric Lie algebra over the real numbers. Recently, it was shown that irreducible Lie algebras whi…
Simply transitive NIL-affine actions of solvable Lie groups
Jonas Deré, Marcos Origlia
Every simply connected and connected solvable Lie group admits a simply transitive action on a nilpotent Lie group via affine transformations. Although the existence is gua…
A note on the structure of underlying Lie algebras
Jonas Deré
Every Lie algebra over a field gives rise to new Lie algebras over any subfield by restricting the scalar multiplication. This paper studies the structure of th…
