## Survey of Differential Logic • 4

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

## Sign Relational Manifolds • Discussion 3

Re: FB | Paradoxology • Alex Shkotin   AS: I see — “sign relation” is a special term for triadic relations of some kind (with some properties);  like this:  thing in first position and thing in second position must refer … Continue reading

## Sign Relational Manifolds • Discussion 2

Re: FB | Paradoxology • Alex Shkotin   AS: Not on a narrow topic, but maybe you have a desire to answer. Hypothesis.  Any material something can be a sign. Is it possible to give an example of something material … Continue reading

## Sign Relational Manifolds • Discussion 1

Semiotic Orbits, Manifolds, Arcs The arc of the semiotic universe is long but it bends towards universal harmony. Re: FB | Semiotics, Books, Links, News • What’s at the End of a Chain of Interpretants? Semiotic manifolds, like physical and … Continue reading

## Sign Relational Manifolds • 5

Let me try to say in intuitive terms what I think is really going on here. The problem we face is as old as the problem of other minds, or intersubjectivity, or even commensurability, and it naturally involves a whole … Continue reading

## Sign Relational Manifolds • 4

Another set of notes I found on this theme strikes me as getting to the point more quickly and though they read a little rough in places I think it may be worth the effort to fill out their general … Continue reading

## Sign Relational Manifolds • 3

I’m not sure when it was I first noticed the relationship between manifolds and semiotics but I distinctly recall the passage in Serge Lang’s Differential and Riemannian Manifolds which brought the triadic character of tangent vectors into high relief.  I … Continue reading

## Sign Relational Manifolds • 2

A sense of how manifolds are applied in practice may be gleaned from the set of excerpts linked below, from Doolin and Martin (1990), Introduction to Differential Geometry for Engineers, which I used in discussing differentiable manifolds with other participants … Continue reading
