OLM 9.1. K or r0?
In TBox 9.1 (TBE, p.171), we derived two conditions for coexistence in the competitive Lotka-Volterra model: one in terms of r0s, and another in term of Ks. These conditions are mathematically equivalent and equally valid. By considering the two arms of feed-back loops separately, we discuss the formal and intuitive difference between the two formulations.
