Reaction networks, or equivalently Petri nets, are a general framework for describing processes in which entities of various kinds interact and turn into other entities. In chemistry, where the reactions are assigned ‘rate constants’, any reaction network gives rise to a nonlinear dynamical system called its ‘rate equation’. Here we generalize these ideas to ‘open’ reaction networks, which allow entities to flow in and out at certain designated inputs and outputs. We treat open reaction networks as morphisms in a category. Composing two such morphisms connects the outputs of the first to the inputs of the second. We construct a functor sending any open reaction network to its corresponding ‘open dynamical system’. This provides a compositional framework for studying the dynamics of reaction networks. We then turn to statics: that is, steady state solutions of open dynamical systems. We construct a ‘black-boxing’ functor that sends any open dynamical system to the relation that it imposes between input and output variables in steady states. This extends our earlier work on black-boxing for Markov processes.

Recurrent Neural Networks (RNN) have been developed for a better understanding and analysis of open dynamical systems. Still the question often arises if RNN are able to map every open dynamical system, which would be desirable for a broad spectrum of applications. In this article we give a proof for the universal approximation ability of RNN in state space model form and even extend it to Error Correction and Normalized Recurrent Neural Networks.

The concept of an open dynamical system as a general model of the development of systems and processes of various nature is proposed. It is based on a new interpretation of M. Mesarovich’s theorem on the decomposition of the Universum, and the concept of observation as an asymmetric relation corresponding to the movement of basis elements of a set of states of a dynamical system between its external and internal space. The element of the basis, according to the concept of geometrodynamics, exists as a vortex in an empty curved internal space of a dynamical system, or as an elementary particle that transfers a quantum of energy when observed. An open dynamical system is defined as a finite dynamical system exchanging observations with the environment, divided into local, representing an inverse dynamical system, and external, where external observations come from. In the intervals between external observations, it exists as a conservative dynamical system. It is regarded the evolution of dynamic systems in the process of expansion and cooling of the Universe: the appearance of elementary particles and atoms, the formation of complex molecules and chain macromolecules, the appearance of living cells, the formation of multicellular organisms, the nervous system and the brain, the appearance of a human and the intellect, the development of society and civilization. With the emergence of life, open dynamic systems became distributed and perform the functions of natural selection of members of the population, and after the appearance of intelligence and the formation of society, they realize social intelligence and become virtual. Threats of uncontrolled behavior of virtual systems, in particular digital artificial intelligence systems, which can neglect the discreteness of space-time due to the use in their design of the classical model of infinitesimal, which do not exist due to the discreteness of space-time, are considered. The incompatibility of the classical model with the discrete model of an open dynamic system is an urgent scientific problem that requires further study.
