Riffs and Rotes, Finite Partial Functions • Overview

Posted on November 14, 2026 by Jon Awbrey

Riffs and Rotes are two species of graph-theoretic structure in a mathematical framework which establishes a bijective Gödel numbering between the positive integers and finite partial functions mapping to .  This framework strips away the standard arithmetic properties of numbers … Continue reading →

Riffs and Rotes • Overview

Posted on November 14, 2026 by Jon Awbrey

Riffs and Rotes are two species of graph-theoretic structure giving visual representation to the primes factorizations of integers, specifically looking at “doubly recursive factorizations”. The Core Concept When a number is broken down into its prime factors, those primes can … Continue reading →

Riffs and Rotes • Happy New Year 2026

Posted on January 1, 2026 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 order correspond to a family of digraphs called riffs and a family of graphs called … Continue reading →

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 →

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 →
