Elliptic CR-manifolds and shear invariant ODE with additional symmetries

Vladimir Ezhov, Gerd Schmalz

We classify the ODEs that correspond to elliptic CR-manifolds with maximal isotropy. It follows that the dimension of the isotropy group of an elliptic CR-manifold can be only 10 (…

Canonical Cartan connection and holomorphic invariants on Engel CR manifolds

Valerii Beloshapka, Vladimir Ezhov, Gerd Schmalz

We describe a complete system of invariants for 4-dimensional CR manifolds of CR dimension 1 and codimension 2 with Engel CR distribution by constructing an explicit canonical Cart…

Simulation of Rapoport's rule for latitudinal species spread

Dietrich Stauffer, Klaus Rohde

Rapoport's rule claims that latitudinal ranges of plant and animal species are generally smaller at low than at high latitudes. However, doubts as to the generality of the rule hav…
