A Computational Approach to Multistationarity in Poly-PL Kinetic Systems

Both the paper and the candidate solution prove dynamic equivalence of the PYK system and its STAR‑MSC PLK transform by distributing each poly-PL term into a separate reaction with the same stoichiometric vector, yielding identical ODE vector fields f* = f. They also correctly deduce the transfer of monostationarity/multistationarity capacity via this equivalence. The steps about canonical equalization of term counts, the choice of M ensuring distinct complexes, and S-invariance are stated and used consistently.
