Geodesic Rosen Continued Fractions [PDF]

open access: yes, 2015
We describe how to represent Rosen continued fractions by paths in a class of graphs that arise naturally in hyperbolic geometry. This representation gives insight into Rosen's original work about words in Hecke groups, and it also helps us to identify ...

The discrete logarithm problem modulo one: cryptanalysing the Ariffin–Abu cryptosystem

open access: yesJournal of Mathematical Cryptology, 2010
The paper provides a cryptanalysis of the AAβ-cryptosystem recently proposed by Ariffin and Abu. The scheme is in essence a key agreement scheme whose security is based on a discrete logarithm problem in the infinite (additive) group ℝ/ℤ (the reals ...

$q$-DEFORMED RATIONALS AND $q$-CONTINUED FRACTIONS

open access: yesForum of Mathematics, Sigma, 2020
We introduce a notion of $q$-deformed rational numbers and $q$-deformed continued fractions. A $q$-deformed rational is encoded by a triangulation of a polygon and can be computed recursively. The recursive formula is analogous to the $q$-deformed Pascal

Continued fractions and class number two

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We use the theory of continued fractions in conjunction with ideal theory (often called the infrastructure) in real quadratic fields to give new class number 2 criteria and link this to a canonical norm-induced quadratic polynomial.

Ramanujan and the Regular Continued Fraction Expansion of Real Numbers [PDF]

open access: yes, 2004
In some recent papers, the authors considered regular continued fractions of the form \[ [a_{0};\underbrace{a,...,a}_{m}, \underbrace{a^{2},...,a^{2}}_{m}, \underbrace{a^{3},...,a^{3}}_{m}, ...

Formulas for the Number of Spanning Trees in a Chain of Cycles

open access: yesSultan Qaboos University Journal for Science, 2010
We give a formula for the number of spanning trees in a chain of cycles that have connected intersection of one edge but where the cycles have variable sizes. The formula uses basic properties of continued fractions.

The Generating Functions for Special Pringsheim Continued Fractions

open access: yesCommunications in Advanced Mathematical Sciences, 2020
In previous works, some relations between Pringsheim continued fractions and vertices of the paths of minimal length on the suborbital graphs $\mathrm{\mathbf{F}}_{u,N}$ were investigated.

Bounding differences in Jager Pairs [PDF]

open access: yes, 2013
Symmetrical subdivisions in the space of Jager Pairs for continued fractions-like expansions will provide us with bounds on their difference. Results will also apply to the classical regular and backwards continued fractions expansions, which are ...

Excursions of diffusion processes and continued fractions [PDF]

open access: yes, 2010
It is well-known that the excursions of a one-dimensional diffusion process can be studied by considering a certain Riccati equation associated with the process.

On the metrical theory of a non-regular continued fraction expansion

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We introduced a new continued fraction expansions in our previous paper. For these expansions, we show the Brodén-Borel-Lévy type formula. Furthermore, we compute the transition probability function from this and the symbolic dynamical system of the ...
