 nderstanding the Regions of Multistaionarity via Symbolic Nonnegativity Ce

 luslararası Cebirsel GEometri Neşesi\n\n\nAbstract\nParameterized ordina
 ry differential equation systems are crucial for modeling in biochemical r
 eaction networks under the assumption of mass-action kinetics. Various que
 stions concerning the signs of multivariate polynomials in positive orthan
 t arise from studying the solutions' qualitative behavior with respect to 
 parameter values. In this work\, we utilize circuit polynomials to find sy
 mbolic certificates of nonnegativity in order to provide further insight i
 nto the number of positive steady states of the n-site phosphorylation cyc
 le model. This is a joint work with Elisenda Feliu\, Nidhi Kaihnsa and Tim
 o de Wolff.\n
