Extremal Topological Indices with Prescribed Degree Sequences

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
This paper explores the extremal properties and bounds of two significant topological indices in graph theory: the Albertson and Sigma indices, with an emphasis on trees and bipartite graphs.

Upper and lower bounds in relator spaces.

open access: yes, 2003
Summary: An ordered pair \(X({\mathcal N}) = (X,{\mathcal N})\) consisting of a nonvoid set \(X\) and a nonvoid family \({\mathcal N}\) of binary relations on \(X\) is called a relator space. Relator spaces are straightforward generalizations not only of uniform spaces, but also of ordered sets. Therefore, in a relator space we can naturally define not
