DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MoRN/25/">Ci
 rcuits of multistationarity in structured enzymatic networks</a>\nby Merce
 des Perez Millan (Universidad de Buenos Aires) as part of Seminar on the M
 athematics of Reaction Networks\n\n\nAbstract\nIn this work we focus on mi
 nimal sets of intermediate species\nand their location in the network to a
 llow for multistationarity in the\ncorresponding mass-action chemical reac
 tion system. This question has also\nbeen studied in Feliu and Wiuf (2013)
  and also in Sadeghimanesh and Feliu\n(2019) using degree theory technique
 s. Our results simplify the analysis\nfor chemical reaction systems with c
 ertain structure\, called "linearly\nbinomial networks" [Dickenstein\, P.M
 .\, Shiu\, Tang (2019)]. We apply our\nresults on several signaling networ
 ks. We also refer to the problem of\nlifting of multistationarity\, and we
  give easy combinatorial conditions\nfor MESSI networks  [P.M.\, Dickenste
 in (2018)] to be linearly binomial.\nThis is joint work with Alicia Dicken
 stein\, Magalí Giaroli and Rick\nRischter.\n
