Abstract
This paper proves a Kantorovich-type inequality on the matrix of the type 12(QH1AQ1QH1A−1Q1+QH1A−1Q1QH1AQ1), where A is an n×n positive definite Hermitian matrix and Q1 is an n×m matrix with rank (Q1)=m. The result is applied to get an extension of the Bauer-Fike inequality on condition numbers of similarities that block diagonalized matrices.
