A slow triangle map with a segment of indifferent fixed points and a complete tree of rational pairs

C Bonanno, A Del Vigna, S Munday - Monatshefte für Mathematik, 2021 - Springer
We study the two-dimensional continued fraction algorithm introduced in Garrity (J Number
Theory 88 (1): 86–103, 2001) and the associated triangle map T, defined on a …

Centered polygon numbers, heptagons and nonagons, and the Robbins numbers

P Barry - arXiv preprint arXiv:2104.01644, 2021 - arxiv.org
In this note, we explore certain determinantal descriptions of the Robbins numbers.
Techniques used for this include continued fractions, Riordan arrays and series inversion …

Generalizing the Minkowski question mark function to a family of multidimensional continued fractions

T Garrity, P Mcdonald - International Journal of Number Theory, 2018 - World Scientific
The Minkowski question mark function?:[0, 1]→[0, 1] is a continuous, strictly increasing, one-
to-one and onto function that has derivative zero almost everywhere. Key to these facts are …

Functional Analysis behind a Family of Multidimensional Continued Fractions: Part I

I Amburg, T Garrity - arXiv preprint arXiv:1703.01589, 2017 - arxiv.org
Triangle partition maps form a family that includes many, if not most, well-known
multidimensional continued fraction algorithms. This paper begins the exploration of the …
