Lumping of components and reactions in a complex reaction network is approached from its standard representation based on the principle of detailed balancing. System conditions related to lumping are made explicit by introducing the notion of lump and classifying the chemical reaction pathways between species as internal or external. Using the groups of species, we define a proper lumping transformation which aggregates the species in the same lump gives rising to pseudospecies. For linear systems the lumpability properties are expressed as an eigenspace condition of the complex reaction network that involves only the properties of external reactions. The strength of boundaries between lumps are also characterized and related to aggregation modes. Physically, we relate the possibility of lumping to the presence of groups of strongly interacting species-the so-called lumping property. Using this property, aggregation of species and reactions in nonlinear reaction systems is also examined, with emphasis on reversible heterogeneous systems. The underlying multitime-scale phenomenon supporting the postulation of lumped mechanisms is highlighted, which opens the way to a new approach to lumping. |
