Dynamical Systems and Their Steady States


As part of the Applied Category Theory 2018 school, Maru Sarazola wrote a blog article on open dynamical systems and their steady states. Check it out:

• Maru Sarazola, Dynamical systems and their steady states, The n-Category Café, 2 April 2018.

She compares two papers:

• David Spivak, The steady states of coupled dynamical systems compose according to matrix arithmetic.

• John Baez and Blake Pollard, A compositional framework for reaction networks, Reviews in Mathematical Physics 29 (2017), 1750028.
(Blog article here.)

It’s great, because I’d never really gotten around to understanding the precise relationship between these two approaches. I wish I knew the answers to the questions she raises at the end!

One Response to Dynamical Systems and Their Steady States

  1. Norbert Weiner suggested looking for transformations that would yield the statistics of output measurements from those of the measurements of the inputs. Following this idea,using the system identification TARMAX model may be a useful way to approach the captioned subject. TARMAX may, also, be useful for discovering not-hidden, just not-considered important variables.
