On the continued fraction expansions of (1+pq)/2 and pq

open access: yesComptes rendus. Mathematique, 2021
The evenness and the values modulo 4 of the lengths of the periods of the continued fraction expansions of p p and √ 2p for p ≡ 3 (mod 4) a prime are known.

Convergence properties of the classical and generalized Rogers-Ramanujan continued fraction [PDF]

open access: yesResearch in Number Theory, 2015
The aim of this paper is to study the convergence and divergence of the Rogers-Ramanujan and the generalized Rogers-Ramanujan continued fractions on the unit circle.

Continued fractions related to a group of linear fractional transformations

open access: yesOpen Mathematics, 2023
There are strong relations between the theory of continued fractions and groups of linear fractional transformations. We consider the group G3,3{G}_{3,3} generated by the linear fractional transformations a=1−1∕za=1-1/z and b=z+2b=z+2.

$q$-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

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}, ...

On the Rank of Universal Quadratic Forms over Real Quadratic Fields

open access: yesDocumenta Mathematica, 2018
We study the minimal number of variables required by a totally positive definite diagonal universal quadratic form over a real quadratic field Q( √ D) and obtain lower and upper bounds for it in terms of certain sums of coefficients of the associated ...

Diophantine approximations and almost periodic functions

open access: yesDemonstratio Mathematica, 2017
In this paper we investigate the asymptotic behaviour of the classical continuous and unbounded almost periodic function in the Lebesgue measure.Using diophantine approximations we show that this function can be estimated by functions of polynomial type ...

Continued fractions and class number two

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 9, Page 565-571, 2001., 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. By doing so, this provides a real quadratic field analogue of the well‐known result by Hendy (1974) for complex quadratic

Growth rate for the expected value of a generalized random Fibonacci sequence [PDF]

open access: yes, 2008
A random Fibonacci sequence is defined by the relation g_n = | g_{n-1} +/- g_{n-2} |, where the +/- sign is chosen by tossing a balanced coin for each n. We generalize these sequences to the case when the coin is unbalanced (denoting by p the probability

Two divisors of (n^2+1)/2 summing up to {\delta}n+{\epsilon}, for {\delta} and {\epsilon} even [PDF]

open access: yes, 2014
In this paper we are dealing with the problem of the existence of two divisors of $(n^2+1)/2$ whose sum is equal to $\delta n+\varepsilon$, in the case when $\delta$ and $\varepsilon$ are even, or more precisely in the case in which $\delta\equiv ...
