چکیده
We study and compare natural generalizations of Euclid's algorithm for polynomials with coefficients in a finite field. This leads to gcd algorithms together their associated continued fraction maps. The act on triples rely two-dimensional versions the Brun, Jacobi–Perron fully subtractive maps, respectively. first provide unified framework these then analyse various costs algorithms, including number iterations two bit-complexity, corresponding representations (the usual sparse one). also maps prove invariance ergodicity Haar measure. deduce estimates truncated trajectories under action obtained thanks transfer operators, we models (gcd maps). Proving that generating functions appear as dominant eigenvalues operator allows indeed fine comparison between models.

Some aspects of multidimensional continued fraction algorithms
Many kinds of algorithms of continued fraction expansions of dimension s(≥ 2) have been studied starting with K.G.J.Jacobi(1804-1851), for example, see [14]. For s = 1, we know Lagrange’s theorem related to periodic continued fractions and real quadratic irrationals. But, even for real cubic irrationalities, there appeared no suitable algorithms (of dimension 2). In this section, we roughly exp...
متن کاملOn the Generalized Rogers–ramanujan Continued Fraction
On page 26 in his lost notebook, Ramanujan states an asymptotic formula for the generalized Rogers–Ramanujan continued fraction. This formula is proved and made slightly more precise. A second primary goal is to prove another continued fraction representation for the Rogers–Ramanujan continued fraction conjectured by R. Blecksmith and J. Brillhart. Two further entries in the lost notebook are e...

Continued fractions lie at the heart of a number of classical algorithms like Euclid's greatest common divisor algorithm or the lattice reduction algorithm of Gauss that constitutes a 2-dimensional generalization. This paper surveys the main properties of functional operators, |transfer operators| due to Ruelle and Mayer (also following L evy, Kuzmin, Wirsing, Hensley, and others) that describe...
متن کامل$3$-dimensional Continued Fraction Algorithms Cheat Sheets
Multidimensional Continued Fraction Algorithms are generalizations of the Euclid algorithm and find iteratively the gcd of two or more numbers. They are defined as linear applications on some subcone of R. We consider multidimensional continued fraction algorithms that acts symmetrically on the positive cone R+ for d = 3. We include well-known and old ones (Poincaré, Brun, Selmer, Fully Subtrac...
متن کاملOn some symmetric multidimensional continued fraction algorithms
We compute explicitly the density of the invariant measure for the Reverse algorithm which is absolutely continuous with respect to Lebesgue measure, using a method proposed by Arnoux and Nogueira. We also apply the same method on the unsorted version of Brun algorithm and Cassaigne algorithm. We illustrate some experimentations on the domain of the natural extension of those algorithms. For so...
