A qualitative study of the steady-state solutions for
a continuous flow stirred tank chemical reactor
SIAM J. Math. Anal. 11 (1980) 316-339.
An approach to the bifurcation of steady-state equilibria using
singularity theory is applied to the problem of multiple equilibria
in a continuous flow stirred tank chemical reactor where the flow
rate is the bifurcation parameter. Under the assumption of a single
first-order exothermic chemical reaction, all the qualitively
different bifurcation diagrams which occur locally are found. They
form the universal unfolding of the singular bifurcation problem
x^3 + \lambda^2 = 0.
