## Survey of Differential Logic • 5

This is a Survey of work in progress on Differential Logic, resources under development toward a more systematic treatment. Differential logic is the component of logic whose object is the description of variation — the aspects of change, difference, distribution, … Continue reading

This is a Survey of blog and wiki posts on Differential Logic, material I plan to develop toward a more compact and systematic account. Elements Differential Propositional Calculus Part 1 • Part 2 • Appendices • References Differential Logic • … Continue reading

Re: Survey of Differential Logic • 3 Re: Laws of Form • Lyle Anderson LA: Thanks for posting this.  Particularly the Differential Logic and Dynamic Systems. It appears this is part of the trail to connecting Forms with Tensors.  Heim … Continue reading

Re: Differential Logic • Comment 7 Re: Laws of Form • Lyle Anderson LA: Differentials and partial differentials over the real numbers work because one can pick two real numbers that are arbitrarily close to one another.  The difference between … Continue reading

Transforms Expanded over Ordinary and Differential Variables As promised in Episode 10, in the next several posts we’ll extend our scope to the full set of boolean functions on two variables and examine how the differential operators and act on that … Continue reading

Re: Differential Logic • Discussion 12 Re: FB | Peirce Society • Χριστο Φόρος Χριστο Φόρος asked whether the difference between qualitative and quantitative information was really all that much of a problem, especially in view of mixed datasets.  As I … Continue reading

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
