Differential Invariants of Carrollian Spacetimes
Boris Kruglikov, Eivind Schneider, Wijnand Steneker
We compute invariants of Carrollian spacetimes, deriving them from the geometry of the screen bundle. For generic Carrollian structures we specify how to generate the entire algebr…
Jet-Density of Finite-Gap Solutions for Classes of BKM Systems
Manuel Quaschner, Wijnand Steneker
We show that jets of initial data can be approximated up to arbitrary order by finite-gap solutions for classes of so-called BKM systems of PDEs introduced by Bolsinov--Konyaev--Ma…
On globally invariant Euler--Lagrange equations for curves
Boris Kruglikov, Eivind Schneider, Wijnand Steneker
Invariant Lagrangians yield invariant Euler-Lagrange equations, and it was discussed in the literature how to compute those using various local methods. The focus of this paper is…
Variationality of conformal geodesics in dimension 3
Boris Kruglikov, Vladimir S. Matveev, Wijnand Steneker
Conformal geodesics form an invariantly defined family of unparametrized curves in a conformal manifold generalizing unparametrized geodesics/paths of projective connections. The e…
Killing Tensors in Koutras-McIntosh Spacetimes
Boris Kruglikov, Wijnand Steneker
The Koutras-McIntosh family of metrics include conformally flat pp-waves and the Wils metric. It appeared in a paper of 1996 by Koutras-McIntosh as an example of a pure radiation s…
