β¦ Synopsis
The standard definition of convergence of an infinite product of scalars is extended to the infinite product P = II~B, of k x k matrices; that is, P is convergent according to the definition given here if and only if there is an integer N such that Bn is invertible for n ~>N and P = lim,~ II~,=uBm is invertible. A family of sufficient conditions for this kind of convergence is given, along with examples showing that they have nontrivial applications. (~) 1999 Elsevier Science B.V. All rights reserved.

Finite dimensional matrices with more columns than rows have no left inverses while those with more rows than columns have no right inverses. We give generalizations of these simple facts to bi-infinite matrices. Our results are then used to obtain density results for p-frames of time-frequency mole
