On knot detection via picture recognition

Our goal is to one day take a photo of a knot and have a phone automatically recognize it. In this expository work, we explain a strategy to approximate this goal, using a mixture of modern machine le...

A Practical Guide to Rigorously Locate Periodic Orbits in Discrete Dynamics

Periodic orbits are important objects of discrete dynamical systems, but finding them is not always easy. We present a self-contained introductory account, aimed at non-experts, to prove their existen...

/Unipotent representations: changing q to -q, II/

Unipotent representations: changing q to -q, II

Consider a Chevalley group over a finite field F_q such that the longest element in the Weyl group is central. In this paper we study the effect of changing q to -q in the polynomials which give the c...

There’s some consanguinity of the feel and flavor of the second with Jim Woodring’s style in Frank, and it’s a specific a note as the underground city called Culloden in the Aeon Flux episode /Chronophasia/

/Schild’s Ladder/, by @gregegansf.bsky.social , was a good read

I was thinking that the scents might exert some influence on how the game runner runs the game, www.oranlooney.com/post/genji-ko/ , but one would need a lot of recorded games to smell that

You might think it’s unlikely for any interesting mathematics to arise from incense appreciation, but that’s only because you’re unfamiliar with the peculiar character of Muromachi (室町) era Japanese n...

Strongly Solving 2048 4x3

2048 is a stochastic single-player game involving 16 cells on a 4 by 4 grid, where a player chooses a direction among up, down, left, and right to obtain a score by merging two tiles with the same num...

the incense guessing game is more or less a discrete dynamical system, so that might be a good place to start?

Incense Week; Kōdō, the Incense Game

While my previous entries have stressed the Buddhist influence and religious usage of incense in Japan, this is misleading. These factors have greatly led to the spread of incense, but the reason it ...

If we can transport representations between (pie in the sky) odorants and jet groups associated with automorphic representations associated with continuous time dynamical systems, it might be a little more natural, if indirect
