Robertson's Example for Stiff Differential Equations

Robertson's example models a representative reaction kinetics as a set of three ordinary diierential equations. After an introduction to the application in chemical engineering, a theoretical stiiness analysis is presented. Its results are connrmed by numerical experiments, and the performances of a non-stii and a stii numerical solver are contrasted. The methods used in this note showcase a possible approach to a problem, which is suspected to be stii. 1 Introduction. In the original paper 5], Robertson states the problem as a system of ordinary diier
