|Reaction-diiusion systems whose kinetics contain a stable limit cycle are an established class of models for a range of oscillatory biological and chemical phenomena. In this paper, the author compares two numerical methods for calculating the oscillatory wake solutions generated by spatially localized perturbations for one particular reaction-diiusion system, of-! type. The two methods are a ...

Oscillatory chemical reactions are of significant importance in chemical and biological sciences. In the present paper we have studied the oscillatory behaviours of two chemical reactions (or oscillators). The first is the classical Lotka model of auto-catalytic chemical reaction and the second is the limit cycle chemical reaction (Tri-molecular reaction) due to Schnakenberg. Beside the determi...
