On weakly Einstein Lie groups
Yunhee Euh, Sinhwi Kim, Yuri Nikolayevsky +1
A Riemannian manifold is called \emph{weakly Einstein} if the tensor is a scalar multiple of the metric tensor . We consider weakly Einstein Lie gro…
Weakly Einstein hypersurfaces in space forms
Jihun Kim, Yuri Nikolayevsky, JeongHyeong Park
A Riemannian manifold is called \emph{weakly Einstein} if the tensor is a scalar multiple of the metric tensor . We give a complete classifi…
Pseudo-Riemannian geodesic orbit nilmanifolds of signature
Zhiqi Chen, Yuri Nikolayevsky, Joseph A. Wolf +1
The geodesic orbit property is useful and interesting in itself, and it plays a key role in Riemannian geometry. It implies homogeneity and has important classes of Riemannian mani…
On triangular biregular degree sequences
Benjamin Egan, Yuri Nikolayevsky
A simple graph is called triangular if every edge of it belongs to a triangle. We conjecture that any graphical degree sequence all terms of which are greater than or equal to 4 ha…
The Structure of Geodesic Orbit Lorentz Nilmanifolds
Yuri Nikolayevsky, Joseph A. Wolf
The geodesic orbit property is useful and interesting in Riemannian geometry. It implies homogeneity and has important classes of Riemannian manifolds as special cases. Those class…
Respectful decompositions of Lie algebras
Grant Cairns, Yuri Nikolayevsky
One of Pierre Molino's principal mathematical achievements was his theory of Riemannian foliations. One of his last papers, published in 2001, showed that his theory could be exten…
