“…KMS and related matrices have received a lot of attention lately with applications to such various fields as statistical mechanics [24,15], differential equations [5,42,43,36,28,41,17], quantum integrable systems [1,10,8] and the Heisenberg group [13,14], among others. There has been a renewed interest in matrices of this type which followed a renewed interest in Toeplitz forms and their connections to orthogonal polynomials.…”
