KINETIC INSTABILITY IN REACTION-DIFFUSION SYSTEMS - THE EFFECT OF TIME-DELAY

The effects of time delay on the transition curve marking the onset of kinetic instability in a class of reaction-diffusion systems are anal ytically evaluated by linearizing the system equations. The analysis i n general shows that the transition curves become multivalued and indi cates considerable shrinkage of the parameter plane where such transit ions can occur. Also, the effect is more severe for higher extents of time delay.
