Abstract
Sufficient conditions for stability of time-varying 1D systems are already well established. This work treats the 2D case in an approach that parallels that of the 1D, yet at the same time reveals the heightened complexity of the extension. When "double exponential stability" is guaranteed for a certain set of homogeneous equations, the 2D system is BIBO stable. The result applies to a generalized form of the Givone-Roesser state-space equations.
