Research output: Contribution to journalArticle


Solution, proposed by Heinz Neudecker and Shuangzhe Liu. Let Xg(N) be the largest eigenvalue of N. We use the relationships (a) tr(A 0 B) = trAtrB, and (b) N (Q) L = Jp (N 0 L)Jp, where N and L are p x p matrices, and the selection matrix Jp with property JpJp = Ip, as defined in Amemiya (1985), Kollo and Neudecker (1993), and Neudecker (1993).
