Conformal structures with -symmetric twistor distribution
Pawel Nurowski, Katja Sagerschnig, Dennis The
For any 4D split-signature conformal structure, there is an induced twistor distribution on the 5D space of all self-dual totally null 2-planes, which is when the conform…
Parabolic quasi-contact cone structures with an infinitesimal symmetry
Omid Makhmali, Katja Sagerschnig
We interpret the property of having an infinitesimal symmetry as a variational property in certain geometric structures. This is achieved by establishing a one-to-one correspondenc…
Modified conformal extensions
Matthias Hammerl, Katja Sagerschnig, Josef Šilhan +1
We present a geometric construction and characterization of -dimensional split-signature conformal structures endowed with a twistor spinor with integrable kernel. The construc…
The geometry of marked contact Engel structures
Gianni Manno, Pawel Nurowski, Katja Sagerschnig
A contact twisted cubic structure (M,C,S) is a 5-dimensional manifold M together with a contact distribution C and a bundle S of twisted cubics that is compatible with the conforma…
Contact manifolds, Lagrangian Grassmannians and PDEs
Olimjon Eshkobilov, Gianni Manno, Giovanni Moreno +1
In this paper we review a geometric approach to PDEs. We mainly focus on scalar PDEs in n independent variables and one dependent variable of order one and two, by insisting on the…
The almost Einstein operator for distributions
Katja Sagerschnig, Travis Willse
For the geometry of oriented distributions , which correspond to regular, normal parabolic geometries of type for a particular par…
