Orthogonality graphs of real Cayley-Dickson algebras. Part I: Doubly alternative zero divisors and their hexagons

Svetlana Zhilina

We study zero divisors whose components alternate strongly pairwise and construct oriented hexagons in the zero divisor graph of an arbitrary real Cayley-Dickson algebra. In case o…

Orthogonality graphs of real Cayley-Dickson algebras. Part II: The subgraph on pairs of basis elements

Svetlana Zhilina

We consider zero divisors of an arbitrary real Cayley-Dickson algebra such that their components are both standard basis elements. We construct inductively the orthogonality graph…

Commuting graphs of Okubo algebras

Svetlana Zhilina, Danil Pavlinov

Commuting graphs of Okubo algebras are considered, and the problem of their connectivity is studied. The commuting graph of a pseudo-octonion algebra over a field…

Relation graphs of the sedenion algebra

Alexander Guterman, Svetlana Zhilina

Let denote the algebra of the sedenions, and denote its orthogonality graph. We observe that any pair of zero divisors in produces a dou…

The algebraic and geometric classification of -Novikov algebras

Hani Abdelwahab, Ivan Kaygorodov, Roman Lubkov

The notion of -Novikov algebras was introduced recently as a generalization of Novikov and bicommutative algebras. It looks like -Novikov algebras have a richer structure tha…

Hamiltonian Sets of Polygonal Paths in Assembly Graphs

A. Guterman, N. Jonoska, E. Kreines +2

We provide four equivalent combinatorial conditions for a simple assembly graph (rigid vertex graph where all vertices are of degree 1 or 4) to have the largest number of Hamiltoni…
