DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MoRN/146/">A
 dding Sequestered Catalysts to Stable or Unstable Linear Stochastic CRNs</
 a>\nby Aidan Howells (Politecnico di Torino) as part of Seminar on the Mat
 hematics of Reaction Networks\n\n\nAbstract\nComputing the stability (that
  is\, positive recurrence or transience) of stochastic mass-action CRNs ca
 n be challenging. One way this challenge manifests is the fact that in gen
 eral\, a reaction network can have very different qualitative stability be
 havior depending on whether it is modeled using deterministic or stochasti
 c mass-action kinetics. One special case where the stability behavior *can
 not* differ is that of linear models with "non-borderline" stability\, whe
 re stability for the ODE model can be understood from straightforward line
 ar algebra computations\, and automatically carries over to the stochastic
  model. However\, purely linear models are rare in applications\, which of
 ten involve some sort of catalysis. In this talk\, we discuss specific cir
 cumstances under which one can add higher-order catalyzed reactions to a s
 tochastic CRN while still preserving stability.\n\nBased on joint work wit
 h Daniele Cappelletti.\n
