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 →

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 →

Relation Theory • Discussion 5

Posted on April 22, 2023 by Jon Awbrey

Re: Survey of Relation Theory Re: Ontolog Forum • Ravi Sharma RS: Is there also an attempt at integrating these relation concepts?  Like a meta‑model of relations? Dear Ravi, I haven’t run across the concept of a meta‑model before so … Continue reading →
