Abstract
We investigate a class of irreversible networks whose chemical species
can be partitioned into two disjoint sets S1 and S2, resulting in a weakly
reversible subnetwork G2 involving only the species S2, and a semi-weaklyreversible network G1; the latter reduces to a weakly reversible network on
formally eliminating the chemical species S2. We introduce a generalized flux
balance condition that can be understood as the natural analogue of the complex
balance condition for weakly reversible networks, and which serves as a tool for
investigating how irreversible networks differ from reversible ones. We also make a
connection between the generalized balance condition and the theory of multiscale
networks by taking S1 to consist of high copy number species (O(N)), where N
is the system size, and S2 to consist of low copy number species (O(1)). We show
how the generalized balance condition of the full stochastic model is related to a
moment balance condition of the corresponding piecewise deterministic Markov
process (PDMP) obtained in the thermodynamic limit N → ∞.
