Re: Category Theory • John Baez (1) (2) JB: One thing I’m interested in is functorially relating purely qualitative models to quantitative ones, or mixed quantitative-qualitative models where you have some numerical information of the sort you describe, but not … Continue reading

Re: Differential Logic • Discussion 9 Let’s look more closely at the “functor” from to and the connection it makes between real and boolean hierarchies of types.  There’s a detailed discussion of this analogy in the article and section linked … Continue reading

Re: Laws of Form • Lyle Anderson Let’s say we’re observing a system at discrete intervals of time and testing whether its state satisfies or falsifies a given predicate or proposition at each moment.  Then and are two state variables … Continue reading

Re: Laws of Form • Lyle Anderson LA: All I am asking is what is your definition of in relation to ‌.  So far I have is what one has to do to get from to or from to ‌.  … Continue reading

Re: Laws of Form • Lyle Anderson A Reader inquired about the relationship between ordinary and differential boolean variables.  I thought it might help to explain how I first came to think about differential logic as a means of describing … Continue reading

Cf: Category Theory • Jon Awbrey I opened a topic in the “logic” stream of “category theory.zulipchat” to discuss differential logic in a category theoretic environment and began by linking a few basic resources. The topic on logical graphs introduced … Continue reading

Re: Differential Logic • 1 Re: FB | Pattern Languages for Systemic Transformation • Steve Kramer SK: Can differential logic be described using category theory?  To what other logical or mathematical modalities does differential logic relate?  Give an example.  Partial … Continue reading

Re: Differential Logic • 5 Re: Laws of Form • Lyle Anderson JA: The differential proposition may be read as saying “change or change or both”.  And this can be recognized as just what you need to do if you … Continue reading

Re: Differential Logic • Discussion 4 Re: Laws of Form • Lyle Anderson JA: The differential proposition is one we use to describe a change of state (or a state of change) from to or the reverse. LA: Does this … Continue reading

Re: Differential Logic • 2 Re: Peirce List • Mauro Bertani MB: About Lobe Connective and Node Connective and their consequences, I have a question: You say that genus and species are evaluated by the proposition The following proposition would … Continue reading
