Pál Rózsa, Roberto Bevilacqua, Paola Favati, Francesco Romani · Birkhäuser Basel eBooks · 1989
In the present paper the authors make an attempt to give a uniform description of the main properties of tridiagonal, band, block tridiagonal and block band matrices and their inverses. Some basic concepts are recalled and also some new results are presented.
