Spectral Geometry for Structural Pattern Recognition [PDF]
, 2010 Graphs are used pervasively in computer science as representations of data with a network or relational structure, where the graph structure provides a flexible representation such that there is no fixed dimensionality for objects. However, the analysis

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Some new relations between Sombor index and graph energy
Examples and CounterexamplesLet G be a graph with {v1,…,vn} being vertices and di being the corresponding vertex degrees. The Sombor index of G is denoted by SO(G) and is defined by SO(G)=∑i∼jdi2+dj2 where i∼j means there exists an edge between the vertices vi and vj.

Skew-spectra and skew energy of various products of graphs [PDF]
Transactions on Combinatorics, 2015 Given a graph $G$, let $G^sigma$ be an oriented graph of $G$ with the orientation $sigma$ and skew-adjacency matrix $S(G^sigma)$. Then the spectrum of $S(G^sigma)$ consisting of all the eigenvalues of $S(G^sigma)$ is called the skew-spectrum of $G ...
