Metric and strong metric dimension in TI-power graphs of finite groups

open access: yesAIMS Mathematics
Given a finite group $ G $ with the identity $ e $, the TI-power graph (trivial intersection power graph) of $ G $ is an undirected graph with vertex set $ G $, in which two distinct vertices $ x $ and $ y $ are adjacent if $ \langle x\rangle\cap \langle

Spatiotemporal Data Graph Modeling and Exploration of Application Scenarios in “Power Grid One Graph”

open access: yesCSEE Journal of Power and Energy Systems
By modeling the spatiotemporal data of the power grid, it is possible to better understand its operational status, identify potential issues and risks, and take timely measures to adjust and optimize the system. Compared to the bus-branch model, the node-

Graph Kernels via Functional Embedding [PDF]

open access: yes, 2014
We propose a representation of graph as a functional object derived from the power iteration of the underlying adjacency matrix. The proposed functional representation is a graph invariant, i.e., the functional remains unchanged under any reordering of ...

Distinguishing Cartesian Powers of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2005
Given a graph $G$, a labeling $c:V(G) \rightarrow \{1, 2, \ldots, d\}$ is said to be $d$-distinguishing if the only element in ${\rm Aut}(G)$ that preserves the labels is the identity. The distinguishing number of $G$, denoted by $D(G)$, is the minimum $d$ such that $G$ has a $d$-distinguishing labeling.

Power Prediction of Regional Photovoltaic Power Stations Based on Meteorological Encryption and Spatio-Temporal Graph Networks

open access: yesEnergies
Distributed photovoltaic (PV) power stations generally lack historical meteorological data, which is one of the main reasons for their insufficient power prediction accuracy.

Perfect codes in power graphs of finite groups

open access: yesOpen Mathematics, 2017
The power graph of a finite group is the graph whose vertex set is the group, two distinct elements being adjacent if one is a power of the other. The enhanced power graph of a finite group is the graph whose vertex set consists of all elements of the ...

Magic powers of graphs [PDF]

open access: yesMathematica Bohemica, 1997
The concept of magic graph was introduced by J. Sedláček. A valuation of the edges of a graph by pairwise different positive numbers is called magic, if the sum of values of edges incident with a given vertex is the same for all vertices. If there exists a magic valuation of a graph \(G\), then \(G\) is called a magic graph.
