摘要：
The existence of stable spiral wave solutions in a spatially discrete lambda - omega system is proven. The waves are shown to exist only if the coupling parameter d is sufficiently small. There is a critical value d(c) such that if d > d(c), the spiral wave solution ceases to exists. This is in agreement with the behavior of such waves in spatially continuous lambda - omega systems on finite domains.
