On Topological Indices in Trees: Fibonacci Degree Sequences and Bounds

Jasem Hamoud, Alexei Belov-Kanel, Duaa Abdullah

In this paper, we have studied bounds based on topological indicators, from which we selected Albertson index $irr$ and the Sigma index $σ$ . The Sigma index was defined th…

Bounds on Trees with Topological Indices Among Degree Sequence

Jasem Hamoud, Alexei Belov-Kanel, Duaa Abdullah

In this paper, we investigate The relationship between the Albertson index and the first Zagreb index for trees. For a tree $T = (V, E)$ with $n = ∣ V ∣$ vertices and $m = ∣ E ∣$ edges, we pr…

Automorphisms of the semigroup of endomorphisms of free associative algebras

A. Kanel-Belov, A. Berzins, R. Lipyanski

Let $A = A (x_{1}, ..., x_{n})$ be a free associative algebra in $A$ freely generated over $K$ by a set $X = {x_{1}, ..., x_{n}}$ , $E n d A$ be the semigroup of endomorphisms of $…
