Obstructions to conformally Einstein metrics in dimensions
A. Rod Gover, Pawel Nurowski
We construct polynomial conformal invariants, the vanishing of which is necessary and sufficient for an -dimensional suitably generic (pseudo-)Riemannian manifold to be conforma…
Projective connections associated with second order ODEs
Ezra T Newman, Pawel Nurowski
We show that every 2nd order ODE defines a 4-parameter family of projective connections on its 2-dimensional solution space. In a special case of ODEs, for which a certain point tr…
Robinson Manifolds as the Lorentzian Analogs of Hermite Manifolds
Pawel Nurowski, Andrzej Trautman
A Lorentzian manifold is defined here as a smooth pseudo-Riemannian manifold with a metric tensor of signature ((2n +1, 1)). A Robinson manifold is a Lorentzian manifold (M) of dim…
Non-vacuum twisting type N metrics
Paweł~Nurowski, Jerzy F. Plebański
A maximally reduced system of equations corresponding to the twisting type N Einstein metrics is given. When the cosmological constant they reduce to the standard equation…
Locally Sasakian Manifolds
Michał Godliński, Wojciech Kopczyński, Paweł Nurowski
We show that every Sasakian manifold in dimension is locally generated by a free real function of variables. This function is a Sasakian analogue of the Kähler potentia…
