Method of invariant manifold

Gorban, A.N., Karlin, I.V., 2003. Method of invariant manifold for chemical kinetics. Chem. Eng. Sci. 

A related approach termed the method of invariant grids (MIG) is also discussed in Gorban and Karlin (2003), Gorban et al. (2004a, c), Chiavazzo et al. (2007,2009) based on the method of invariant manifold (MIM). In MIG, a quasi-equilibrium approach is used to define a first approximation to the SIM on a grid in concentration space, and then improved estimations of the SIM are obtained using either Newton iteration or relaxation methods. The MIG was compared to CSP-based methods, the ILDM method and the entropy-based methods in Chiavazzo et al. (2007).
