Survey of Relation Theory • 9

Posted on May 5, 2025 by Jon Awbrey

In the present Survey of blog and wiki resources for Relation Theory, relations are viewed from the perspective of combinatorics, in other words, as a topic in discrete mathematics, with special attention to finite structures and concrete set‑theoretic constructions, many … Continue reading →

Survey of Animated Logical Graphs • 8

Posted on May 2, 2025 by Jon Awbrey

This is a Survey of blog and wiki posts on Logical Graphs, encompassing several families of graph‑theoretic structures originally developed by Charles S. Peirce as graphical formal languages or visual styles of syntax amenable to interpretation for logical applications. Beginnings Logical Graphs … Continue reading →

Riffs and Rotes • Happy New Year 2025

Posted on January 1, 2025 by Jon Awbrey

No information is lost by dropping the terminal 1s.  Thus we may write the following form. The article linked below tells how forms of that sort correspond to a family of digraphs called riffs and a family of graphs called … Continue reading →

Differential Propositional Calculus • Discussion 9

Posted on January 21, 2024 by Jon Awbrey

Consider what effects that might conceivably have practical bearings you conceive the objects of your conception to have.  Then, your conception of those effects is the whole of your conception of the object. — C.S. Peirce • The Maxim of … Continue reading →

Transformations of Discourse It is understandable that an engineer should be completely absorbed in his speciality, instead of pouring himself out into the freedom and vastness of the world of thought, even though his machines are being sent off to … Continue reading →
