Spectral Gap for Complete Graphs: Upper and Lower Estimates
2015 (English)Report (Other academic)
Lower and upper estimates for the spectral of the Laplacian on a compact metric graph are discussedà New upper estimates are presented and existing lower estimates are reviewedà The accuracy of these estimates is checked in the case of complete not necessarily regular graph with large number of vertices.
