A sharp lower bound on the signless Laplacian index of graphs with (κ,τ)-regular sets
Special Matrices, 2018 A new lower bound on the largest eigenvalue of the signless Laplacian spectra for graphs with at least one (κ,τ)regular set is introduced and applied to the recognition of non-Hamiltonian graphs or graphs without a perfect matching.

Perfect Matchings in Random Octagonal Chain Graphs
Journal of Mathematics, 2021 A perfect matching of a (molecule) graph G is a set of independent edges covering all vertices in G. In this paper, we establish a simple formula for the expected value of the number of perfect matchings in random octagonal chain graphs and present the ...

Cyclewidth and the Grid Theorem for Perfect Matching Width of Bipartite Graphs [PDF]
International Workshop on Graph-Theoretic Concepts in Computer Science, 2019 A connected graph G is called matching covered if every edge of G is contained in a perfect matching. Perfect matching width is a width parameter for matching covered graphs based on a branch decomposition.

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

OPEN PACKING NUMBER FOR SOME CLASSES OF PERFECT GRAPHS
Ural Mathematical Journal, 2020 Let \(G\) be a graph with the vertex set \(V(G)\). A subset \(S\) of \(V(G)\) is an open packing set of \(G\) if every pair of vertices in \(S\) has no common neighbor in \(G.\) The maximum cardinality of an open packing set of \(G\) is the open ...

Perfect matchings in inhomogeneous random bipartite graphs in random environment
Cubo, 2022 In this note we study inhomogeneous random bipartite graphs in random environment. These graphs can be thought of as an extension of the classical Erd\H os-R\'enyi random bipartite graphs in a random environment.
