Introduction to Algebraic Connectivity and Fiedler Vector

Explore the fundamental concepts of algebraic connectivity and Fiedler vectors in this 24-minute lecture from NPTEL-NOC IITM. Learn about algebraic connectivity, defined as the second smallest eigenvalue of the Laplacian matrix, and understand its significance in graph theory and network analysis. Discover the properties and applications of the Fiedler vector, which corresponds to the eigenvector associated with this second smallest eigenvalue. Gain insights into how these mathematical concepts are used to analyze connectivity, clustering, and structural properties of graphs and networks.
