• (2003) We determine analytically the modulus of the second eigenvalue for the web hyperlink matrix used by Google for computing PageRank. Specifically, we prove the following statement: “For any matrix A = cP + (1 − c)E T , where P is an n × n row-stochastic matrix, E is a nonnegative n×n rank-one row-stochastic matrix, and 0 c 1, the second eigenvalue of A has modulus | 2| c. Furthermore, if P has at least two irreducible closed subsets, the second eigenvalue 2 = c. ...

• One of my students asked me the other day "What is an Eigenvalue?" I did not take linear algebra in college and could not answer him. Could someone explain to me in terms where I can explain it to my student what an Eigenvalue is? Warmest Regards, Charlie Higgins Date: 04/06/98 at 08:13:58 From: Doctor Jerry Subject: Re: Eigenvalues Hi Charlie, If A is an n by n matrix, then a real or complex number w is an eigenvalue of A if there is a nonzero n by 1 matrix Y for which A*Y = w*Y. ... We have: (a-k1)x + by = 0 (a-k1)x = - by x -b --- = ---- y a-k1 and we get: u1 = |x| = | b | |y| |k1-a| and so associated with the eigenvalue k1 we get the eigenvector u1 given by: u1 = | b | |k1-a| and there will be another eigenvector u2 associated with the eigenvalue k2. ...
