Matrix Measures and Random Walks with a Block Tridiagonal Transition Matrix

SIAM Journal on Matrix Analysis and Applications, 2007
Summary: We study the connection between matrix measures and random walks with a block tridiagonal transition matrix. We derive sufficient conditions such that the blocks of the \(n\)-step block tridiagonal transition matrix of the Markov chain can be represented as integrals with respect to a matrix valued spectral measure.

The inverse of a block-circulant matrix

IEEE Transactions on Antennas and Propagation, 1983
The inverse A^{-1} of a block-circulant matrix (BCM) A is given in a closed form, by using the fact that a BCM is a combination of permutation matrices, whose eigenvalues and eigenvectors are found with the help of the complex roots of unity. Special results are also given when A is block symmetric or symmetric.
