# On the multistationarity of chemical reaction networks

## TL;DR

This paper proposes a new conjecture outlining a necessary condition for chemical reaction networks to exhibit multistationarity, supported by examples and extending known results for monotonic kinetics.

## Contribution

It introduces a novel conjecture on multistationarity conditions in chemical networks, expanding understanding beyond strictly monotonic kinetics.

## Key findings

- The conjecture is supported by multiple illustrative examples.
- It extends the known theorem for strictly monotonic kinetics.
- Provides a new perspective on conditions for multistationarity.

## Abstract

We present a new conjecture about a necessary condition that a (bio)chemical network has to satisfy for it to exhibit multistationarity. According to a Theorem of Feliu and Wiuf [27, 12], the conjecture is known for strictly monotonic kinetics. We give several examples illustrating our conjecture.
