In this discussion paper we argue that category theory may play a useful role in formulating, and perhaps proving, results in ergodic theory, topogical dynamics and open systems theory (control theory). As examples, we show how to characterize Kolmogorov–Sinai, Shannon entropy and topological entropy as the unique functors to the nonnegative reals satisfying some natural conditions. We also provide a purely categorical proof of the existence of the maximal equicontinuous factor in topological dynamics. We then show how to define open systems (that can interact with their environment), interconnect them, and define control problems for them in a unified way.

This article develops some novel extensions of the classical Tavistock model of organisational psychodynamics. The classical model privileges the emotion of anxiety as the primary trigger for psychosocial experiences in organisations. While this approach has been very generative, it has also been limiting, since there are several other important emotions that shape how people take up their work and their roles in organisations. The article shows how open systems theory and sociotechnical thinking emerge logically from the anxiety model by highlighting how organisations become functional, and work becomes satisfying. The article goes on to explore how desire as a feeling for the future, stimulates such feelings as danger, dread, and excitement. When these feelings become dispositive, they generate experiences associated with anxiety, and the primary risk, as well as the potential for developmental politics. Politics can be developmental rather than defensive when executives create settings where conflict is seen as transaction and rationality as an achievement. This article explores these issues through the use of case vignettes in the public domain, including a skunk works project in Data General, and leadership struggles and strategy dilemmas in Apple, IBM, and Polaroid.

It is common, when dealing with quantum processes involving a subsystem of a much larger composite closed system, to treat them as effectively memory-less (Markovian). While open systems theory tells us that non-Markovian processes should be the norm, the ubiquity of Markovian processes is undeniable. Here, without resorting to the Born-Markov assumption of weak coupling or making any approximations, we formally prove that processes are close to Markovian ones, when the subsystem is sufficiently small compared to the remainder of the composite, with a probability that tends to unity exponentially in the size of the latter. We also show that, for a fixed global system size, it may not be possible to neglect non-Markovian effects when the process is allowed to continue for long enough. However, detecting non-Markovianity for such processes would usually require non-trivial entangling resources. Our results have foundational importance, as they give birth to almost Markovian processes from composite closed dynamics, and to obtain them we introduce a new notion of equilibration that is far stronger than the conventional one and show that this stronger equilibration is attained.
