Abstract :

The study of Chemical Reaction Networks (CRN's) is a very active field.
Earlier well-known results [1,2] identify a topological
quantity called deficiency, for any CRN, which, when exactly equal to zero,
leads to a factorized steady-state for these networks.
However, not much is known for networks, which have non-zero deficiency.
This talk will focus on introducing some of these earlier works as
well as describing some of our own recent results [3] on how
to obtain the steady states, even for networks with non-zero deficiency
by looking at the full moment-hierarchy for the factorial moments.
