Left-invariant CR structures on 3-dimensional Lie groups
Gil Bor, Howard Jacobowitz
The systematic study of CR manifolds originated in two pioneering 1932 papers of Élie Cartan. In the first, Cartan classifies all homogeneous CR 3-manifolds, the most well-known ca…
Loose ends in a strong force 3-body problem
Connor Jackman
Up to symmetries, the orbits of three equal masses under an inverse cube force with zero angular momentum and constant moment of inertia can be reparametrized as the geodesics of a…
Hill's equation, tire tracks and rolling cones
Gil Bor, Mark Levi
Louis Poinsot has shown in 1854 that the motion of a rigid body, with one of its points fixed, can be described as the rolling without slipping of one cone, the 'body cone', along…
Short survey on the existence of slices for the space of Riemannian metrics
Diego Corro, Jan-Bernhard Kordaß
We review the well-known slice theorem of Ebin for the action of the diffeomorphism group on the space of Riemannian metrics of a closed manifold. We present advances in the study…
Torus actions on Alexandrov 4-spaces
Diego Corro, Jesús Núñez-Zimbrón, Masoumeh Zarei
We obtain an equivariant classification for orientable, closed, four-dimensional Alexandrov spaces admitting an isometric torus action. This generalizes the equivariant classificat…
