WebThe algebraic connectivity (also known as Fiedler value or Fiedler eigenvalue after Miroslav Fiedler) of a graph G is the second-smallest eigenvalue (counting multiple eigenvalues separately) of the Laplacian matrix of G. [1] This eigenvalue is greater than 0 if and only if G is a connected graph. This is a corollary to the fact that the number ... Web1 corresponding to eigenvalue 2. A 2I= 0 4 0 1 x 1 = 0 0 By looking at the rst row, we see that x 1 = 1 0 is a solution. We check that this works by looking at the second row. Thus we’ve found the eigenvector x 1 = 1 0 corresponding to eigenvalue 1 = 2. Let’s nd the eigenvector x 2 corresponding to eigenvalue 2 = 3. We do
