Classification of the traceless Ricci tensor in 4-dimensional pseudo-Riemannian spaces of neutral signature
Adam Chudecki
The traceless Ricci tensor in 4-dimensional pseudo-Riemannian spaces equipped with the metric of the neutral signature is analyzed. Its algebraic classification is given.…

On geometry of congruences of null strings in 4-dimensional complex and real pseudo-Riemannian spaces
Adam Chudecki
4-dimensional spaces equipped with 2-dimensional (complex holomorphic or real smooth) completely integrable distributions are considered. The integral manifolds of such distributio…

On some examples of para-Hermite and para-Kähler Einstein spaces with
Adam Chudecki
Spaces equipped with two complementary (distinct) congruences of self-dual null strings and at least one congruence of anti-self-dual null strings are considered. It is shown that…
