Spectral Extrema of Graphs With Fixed Size: Forbidden a Fan Graph, a Friendship Graph, or a Theta Graph

Journal of Graph Theory
ABSTRACTIt is well‐known that Brualdi‐Hoffman‐Turán‐type problem inquiries about the maximum spectral radius of an ‐free graph with edges. This can be regarded as a spectral characterization of the existence of the subgraph within . A significant contribution to this problem was made by Nikiforov (2002).

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Edge δ− Graceful Labeling for Some Cyclic-Related Graphs

Advances in Mathematical Physics, 2020
In this paper, we introduce a new type of labeling of a graph G with p vertices and q edges called edge δ− graceful labeling, for any positive integer δ, as a bijective mapping f of the edge set EG into the set δ,2δ,3δ,⋯,qδ such that the induced mapping ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Path Energy Bounds For Hub-Centric Graphs Of Order 2n+1 With Algorithmic Computation

Scientific Annals of Computer Science
This study investigates the path energy bounds of hub-centric graph families of order (2n+1), denoted by ℋ_{2n+1}. The path energy is defined as the absolute sum of the eigenvalues of the path adjacency matrix A_p(ℋ_{2n+1}), where each entry p_{ij ...

Some New Topological Indices of Friendship Graph

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: In this paper we compute the first and second Kulli-Basava indices, hyper Kulli-Basava indices, some connectivity Kulli-Basava indices, geometric-arithmetic Kulli-Basava indices and reciprocal Kulli-Basava indices of the friendship graph.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Brouwer's conjecture for the sum of the k largest Laplacian eigenvalues of some graphs

Open Mathematics
Let GG be a graph with n(G)n\left(G) vertices and e(G)e\left(G) edges, and Sk(G){S}_{k}\left(G) be the sum of the kk largest Laplacian eigenvalues of GG. Brouwer conjectured that Sk(G)≤e(G)+k+12{S}_{k}\left(G)\le e\left(G)+\left(\phantom{\rule[-0.75em]{}{
