Breakdown of Fault-Tolerance in Boron Nanotube Lattices

Published on January 25, 2023

Just like a self-stable system that can replace a faulty unit with a working one, boron nanotube lattices have shown their fault-tolerant nature. Although the exact values of fault-tolerant metric dimensions might be tricky to compute, recent research has found closed formulas for the fault-tolerant metric dimension of triangular and alpha boron nanotubes. These lattices are created by cutting vertically through the tubes. The fascinating result is that both types of tubes exhibit a constant fault tolerance metric dimension of 4, no matter the shape or structure of the lattice! This discovery further emphasizes the resilience and potential applications of nanotube structures in various fields, from computer science to mathematics.

The concept of resolving set and metric basis has been very successful because of multi-purpose applications both in computer and mathematical sciences. A system in which failure of any single unit, another chain of units not containing the faulty unit can replace the originally used chain is called a fault-tolerant self-stable system. Recent research studies reveal that the problem of finding metric dimension is NP-hard for general graphs and the problem of computing the exact values of fault-tolerant metric dimension seems to be even harder although some bounds can be computed rather easily. In this article, we compute closed formulas for the fault-tolerant metric dimension of lattices of two types of boron nanotubes, namely triangular and alpha boron. These lattices are formed by cutting the tubes vertically. We conclude that both tubes have constant fault tolerance metric dimension 4.
