Graphs: Structure, Spectra, and Extremes
This seminar series explores the deep interplay between graph structure, spectral invariants, and extremal constraints — bringing together discrete curvature, spectral graph theory, and extremal combinatorics to uncover the hidden laws governing complex networks.
