Accurate prediction of tensorial spectra using equivariant graph neural network [PDF]
Nature CommunicationsOptical spectroscopies provide a powerful means to probe light-matter interactions and complex electronic features that are crucial for the development and optimization of optoelectronic devices, where performance is closely tied to the underlying ...

Indexing hierarchical structures using graph spectra [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2005 Hierarchical image structures are abundant in computer vision and have been used to encode part structure, scale spaces, and a variety of multiresolution features. In this paper, we describe a framework for indexing such representations that embeds the topological structure of a directed acyclic graph (DAG) into a low-dimensional vector space. Based on

Spectra of Graphs Resulting from Various Graph Operations and Products: a Survey
Special Matrices, 2018 Let G be a graph on n vertices and A(G), L(G), and |L|(G) be the adjacency matrix, Laplacian matrix and signless Laplacian matrix of G, respectively. The paper is essentially a survey of known results about the spectra of the adjacency, Laplacian and ...

Associative spectra of graph algebras I [PDF]
Journal of Algebraic Combinatorics, 2021 AbstractAssociative spectra of graph algebras are examined with the help of homomorphisms of DFS trees. Undirected graphs are classified according to the associative spectra of their graph algebras; there are only three distinct possibilities: constant 1, powers of 2, and Catalan numbers.

Nullity and Bounds to the Nullity of Dendrimer Graphs [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 In this paper, a high zero-sum weighting is applied to evaluate the nullity of a dendrimer graph for some special graphs such as cycles, paths, complete graphs, complete bipartite graphs and star graphs.

SPECTRA OF PRINCIPAL GRAPHS [PDF]
International Journal of Mathematics, 2001 We show that if the adjacency matrices of the two principal graphs of a finite index subfactor are regarded as (necessarily bounded, self-adjoint) operators on the ℓ2 spaces over their vertex sets, then their spectral measures, when restricted to the complement of {0}, are mutually absolutely continuous.
