Riffs and Rotes • Happy New Year 2024

Posted on January 2, 2024 by Jon Awbrey

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

Riffs and Rotes • 59281

Posted on September 5, 2021 by Jon Awbrey

Re: Persiflage • 59281 Numberfile • What’s Special About 59,281? If is prime then the decimal expansion of repeats, so it makes sense to talk about the “average” of the digits of   The average can be bigger than equal … Continue reading →

Riffs and Rotes • Happy New Year 2021

Posted on January 3, 2021 by Jon Awbrey

Apart from their abstract beauty, Riffs and Rotes are structures I discovered while playing around with Gödel numberings of graphs and digraphs.  To my way of thinking they bear a deep connection to the mathematical infrastructure of logic.  Here are … Continue reading →

Re: Scott Aaronson • The Busy Beaver Frontier All my favorite integer sequences, some very fast growing, spring from the “lambda point” where graph theory, logic, and number theory meet.  My fascination with them goes back to a time when … Continue reading →

Posted on September 16, 2019 by Jon Awbrey

Prompted by a recent discussion of prime numbers and complex dynamics on one of the Santa Fe Institute’s FaceBook pages, I posted a link to an old project of mine, going back to a time when I was first learning programming … Continue reading →

Re: R.J. Lipton • Failure Of Unique Factorization My favorite question in this realm is how much of the linear ordering of the natural numbers is purely combinatorial, where we eliminate all the structure that isn’t purely combinatorial via the … Continue reading →

Re: Michael Harris • Language About Language But then inevitably I find myself wondering whether a proof assistant, or even a formal system, can make the distinction between “technical” and “fundamental” questions.  There seems to be no logical distinction.  The … Continue reading →

Re: Timothy Chow • Shifting Paradigms? 2014 Jul 31 I can’t remember when I first started playing with Gödel codings of graph-theoretic structures, which arose in logical and computational settings, but I remember being egged on in that direction by … Continue reading →
