Resonance graphs of catacondensed even ring systems [PDF]

Applied Mathematics and Computation, 2020
A catacondensed even ring system (shortly CERS) is a simple bipartite 2-connected outerplanar graph with all vertices of degree 2 or 3. In this paper, we investigate the resonance graphs (also called $Z$-transformation graphs) of CERS and firstly show that two even ring chains are resonantly equivalent iff their resonance graphs are isomorphic.

Resonance Graphs and a Binary Coding of Perfect Matchings of Outerplane Bipartite Graphs

Match Communications in Mathematical and in Computer Chemistry, 2023
The aim of this paper is to investigate resonance graphs of 2- connected outerplane bipartite graphs, which include various families of molecular graphs. Firstly, we present an algorithm for a binary coding of perfect matchings of these graphs. Further, 2- connected outerplane bipartite graphs with isomorphic resonance graphs are considered.

Functional brain networks before the onset of psychosis : a prospective fMRI study with graph theoretical analysis [PDF]

, 2012
Individuals with an at-risk mental state (ARMS) have a risk of developing a psychotic disorder significantly greater than the general population. However, it is not currently possible to predict which ARMS individuals will develop psychosis from clinical

A maximum resonant set of polyomino graphs

Discussiones Mathematicae Graph Theory, 2016
A polyomino graph $H$ is a connected finite subgraph of the infinite plane grid such that each finite face is surrounded by a regular square of side length one and each edge belongs to at least one square. In this paper, we show that if $K$ is a maximum resonant set of $H$, then $H-K$ has a unique perfect matching.

A Laplacian Approach to Locate Source of Forced Oscillations Under Resonance Conditions Based on Energy-Driven Multilateral Interactive Pattern

Iranian Journal of Electrical and Electronic Engineering, 2022
The most challenging circumstance of forced oscillations (FOs) is when the power system is forced to oscillate at its natural frequencies. This paper uses a novel PMU data-driven mechanism to pinpoint the source of such phenomena under resonance ...
