Reconfiguring spanning and induced subgraphs [PDF]

open access: yesTheoretical Computer Science, 2018
Subgraph reconfiguration is a family of problems focusing on the reachability of the solution space in which feasible solutions are subgraphs, represented either as sets of vertices or sets of edges, satisfying a prescribed graph structure property. Although there has been previous work that can be categorized as subgraph reconfiguration, most of the ...

Groups for which the noncommuting graph is a split graph [PDF]

open access: yesInternational Journal of Group Theory, 2017
The noncommuting graph $nabla (G)$ of a group $G$ is a simple graph whose vertex set is the set of noncentral elements of $G$ and the edges of which are the ones connecting two noncommuting elements. We determine here, up to isomorphism, the structure of

Induced subgraph and eigenvalues of some signed graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
Hao Huang proved the Sensitivity Conjecture in [Induced graphs of the hypercube and a proof of the Sensitivity Conjecture, Annals of Mathematics, 190 (2019), 949-955] by signed graph spectral method.

Finding a heaviest vertex-weighted triangle is not harder than matrix multiplication [PDF]

open access: yes, 2009
We show that a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(n(omega) + n(2+o(1))), where omega is the exponent of the fastest matrix multiplication algorithm. By the currently

Efficient Streaming Subgraph Isomorphism with Graph NeuralNetworks

open access: yes, 2021
Queries to detect isomorphic subgraphs are important in graphbased data management. While the problem of subgraph isomorphism search has received considerable attention for the static setting of a single query, or a batch thereof, existing approaches do ...

Beyond Distributed Subgraph Detection: Induced Subgraphs, Multicolored Problems and Graph Parameters [PDF]

open access: yes, 2022
Subgraph detection has recently been one of the most studied problems in the CONGEST model of distributed computing. In this work, we study the distributed complexity of problems closely related to subgraph detection, mainly focusing on induced subgraph ...

On induced subgraphs of the Hamming graph [PDF]

open access: yesJournal of Graph Theory, 2020
AbstractIn connection with his solution of the Sensitivity Conjecture, Hao Huang (arXiv: 1907.00847, 2019) asked the following question: Given a graph with high symmetry, what can we say about the smallest maximum degree of induced subgraphs of with vertices, where denotes the size of the largest independent set in ?

Graphs in which every c edges that form a tree are chords of a common cycle

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Consider the k-connected graphs G in which every edges that form a particular type of induced subgraph must all be chords of a common cycle of G. Extending a few known partial results with and new results exploit the structure of the specified type of ...

Supervised chemical graph mining improves drug-induced liver injury prediction

open access: yesiScience, 2023
Summary: Drug-induced liver injury (DILI) is the main cause of drug failure in clinical trials. The characterization of toxic compounds in terms of chemical structure is important because compounds can be metabolized to toxic substances in the liver ...
