Tight Frame Graphs Arising as Line Graphs | Veronika Furst
; Howard Grotts
; | Date: |
17 Jul 2020 | Abstract: | Dual multiplicity graphs are those simple, undirected graphs that have a
weighted Hermitian adjacency matrix with only two distinct eigenvalues. From
the point of view of frame theory, their characterization can be restated as
which graphs have a representation by a tight frame. In this paper, we classify
certain line graphs that are tight frame graphs and improve a previous result
on the embedding of frame graphs in tight frame graphs. | Source: | arXiv, 2007.8673 | Services: | Forum | Review | PDF | Favorites |
