[PDF][PDF] On Hermite's problem, Jacobi-Perron type algorithms, and Dirichlet groups

O Karpenkov - Acta Arith., 2022 - core.ac.uk
A well-known result of Lagrange (1770) characterises quadratic irrationalities as those real
numbers that can be written as periodic continued fractions. Hermite asked in 1848 if there …

Periodicity of general multidimensional continued fractions using repetend matrix form

H Řada, Š Starosta, V Kala - Expositiones Mathematicae, 2024 - Elsevier
We consider expansions of vectors by a general class of multidimensional continued fraction
algorithms. If the expansion is eventually periodic, then we describe the possible structure of …

On a periodic Jacobi–Perron type algorithm

O Karpenkov - Monatshefte für Mathematik, 2024 - Springer
Abstract In 1848 Ch. Hermite formulated a question on periodic representation of cubic
numbers. In this paper we introduce a new Jacobi–Perron type algorithm that provides …

On the finiteness and periodicity of the 𝑝-adic Jacobi–Perron algorithm

N Murru, L Terracini - Mathematics of Computation, 2020 - ams.org
Multidimensional continued fractions (MCFs) were introduced by Jacobi and Perron to
obtain periodic representations for algebraic irrationals, analogous to the case of simple …

On Hermite's problem, Jacobi-Perron type algorithms, and Dirichlet groups

O Karpenkov - arXiv preprint arXiv:2101.12707, 2021 - arxiv.org
In 1848 Ch.~ Hermite asked if there exists some way to write cubic irrationalities periodically.
A little later in order to approach the problem CGJ~ Jacobi and O.~ Perron generalized the …

Linear recurrence sequences and periodicity of multidimensional continued fractions

N Murru - The Ramanujan Journal, 2017 - Springer
Multidimensional continued fractions generalize classical continued fractions with the aim of
providing periodic representations of algebraic irrationalities by means of integer …

Simultaneous approximations to p-adic numbers and algebraic dependence via multidimensional continued fractions

N Murru, L Terracini - The Ramanujan Journal, 2021 - Springer
Unlike the real case, there are not many studies and general techniques for providing
simultaneous approximations in the field of p-adic numbers\mathbb Q_p Q p. Here, we study …

Approximations of algebraic irrationalities with matrices

S Barbero, U Cerruti, N Murru - Experimental Mathematics, 2021 - Taylor & Francis
We discuss the use of matrices for providing sequences of rationals that approximate
algebraic irrationalities. In particular, we study the regular representation of algebraic …
