Abstract
We consider the model of catalysis due to Ziff, Gulari, and Barshad [P hys. Rev. Lett. 56, 2553 (1986)] as a pattern formation problem: We fi nd that the model supports trigger waves, and we examine the dependenc e of the wave velocity on diffusion. In addition to the usual interfac e width, there is a statistical broadening of the wave front that incr eases in time as t(1/3).
