Title: | A note on the multiplicities of the eigenvalues of a graph | Authors: | Fonseca, C. M. da | Issue Date: | 2005 | Citation: | Linear and Multilinear Algebra - Taylor & Francis. 53:4 (2005) 303-307 | Abstract: | Let A(G) be a Hermitian matrix whose graph is a given graph G. From the interlacing theorem, it is known that mA(G\1)(θ) ≥ mA(G)(θ) is the multiplicity of the eigenvalue???of A(G). In this note we improve this inequality for some paths with more than one vertex. | URI: | https://hdl.handle.net/10316/8980 | Rights: | openAccess |
