What are the potential effects on the dynamics of a CRN of adding new reactions and/or species\, or modifying r eactions? Such results allow us to make claims about large networks based on their subnetworks. This talk will focus on a particular inheritance res ult: under mild assumptions\, splitting reactions and inserting intermedia te complexes preserves the capacity of a mass action CRN for nondegenerate multistationarity and oscillation. This allows us to claim\, more general ly\, that introducing enzymatic mechanisms into mass action systems preser ves their capacity for these behaviours. The main result is motivated by t he fact that intermediates are often omitted from CRN models in biology\, but the effects of leaving out intermediates are not always well understoo d.\n LOCATION:https://researchseminars.org/talk/MoRN/57/ END:VEVENT END:VCALENDAR
