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…
Canonical curves and Kropina metrics in Lagrangian contact geometry
T. Ma, K. J. Flood, V. S. Matveev +1
We present a Fefferman-type construction from Lagrangian contact to conformal structures and examine several related topics. In particular, we concentrate on describing the canonic…
Conformal theory of curves with tractors
Josef Šilhan, Vojtěch Žádník
We present the general theory of curves in conformal geometry using tractor calculus. This primarily involves a tractorial determination of distinguished parametrizations and relat…
Fefferman-Graham ambient metrics of Patterson-Walker metrics
Matthias Hammerl, Katja Sagerschnig, Josef Šilhan +2
Given an -dimensional manifold with an affine connection , we show that the associated Patterson-Walker metric on admits a global and explicit Fefferman-Graham…
Conformal Patterson-Walker metrics
Matthias Hammerl, Katja Sagerschnig, Josef Šilhan +2
The classical Patterson-Walker construction of a split-signature (pseudo-)Riemannian structure from a given torsion-free affine connection is generalized to a construction of a spl…
A Projective-to-Conformal Fefferman-Type Construction
Matthias Hammerl, Katja Sagerschnig, Josef Šilhan +2
We study a Fefferman-type construction based on the inclusion of Lie groups into . The construction associates a split-signature -confor…
