1. The magnetic discrete Laplacian inferred from the Gauß–Bonnet operator and application.

Author

Athmouni, Nassim, Baloudi, Hatem, Damak, Mondher, and Ennaceur, Marwa

Subjects
*WEIGHTED graphs, *GRAPH theory, *SPECTRAL theory
Abstract

We consider the notion of χ -completeness of a locally finite graph and we extend this notion to the weighted magnetic graph. Moreover, we establish a link between the magnetic adjacency matrix on line graph and the magnetic discrete Laplacian on 1-forms. [ABSTRACT FROM AUTHOR]

2. The graphs with all but two eigenvalues equal to $$-2$$ or 0.

Author

Cioabă, Sebastian, Haemers, Willem, and Vermette, Jason

Subjects
EIGENVALUES, GRAPHIC methods, EIGENVECTORS, GRAPH theory, PARALLEL algorithms
Abstract

We determine all graphs for which the adjacency matrix has at most two eigenvalues (multiplicities included) not equal to $$-2$$ , or 0, and determine which of these graphs are determined by their adjacency spectrum. [ABSTRACT FROM AUTHOR]
