Inspired by the philosophy of systems biology, we introduce a categorical formalism for biochemical regulatory networks, using signed graphs to model the networks and signed functors to describe occurrences of one network in another. We then give a functorial semantics to regulatory networks using Lotka-Volterra systems of differential equations. Read more
