Suppose rate of change of coefficients of a linear time-variant system modeled via a difference equation is restricted. The work presented herein is an attempt at developing an algorithm that determines regions in coefficient-space where such a system is guaranteed to be globally asymptotically stable. Such information can be extremely useful in many applications. Some previously published related results are consolidated as well.
