[more] Â© 2017 Australian Mathematical Publishing Association Inc.In this short note, considering functions, we show that taking an asymptotic viewpoint allows one to prove strong transcendence statements in many general situations. In particular, as a consequence of a more general result, we show that if F(z) Â¿ C[[z]] is a power series with coefficients from a finite set, then F(z) is either rational or it is transcendental over the field of meromorphic functions.

In order to provide such a classification, we introduce the notion of a growth exponent for kregular sequences and show that this exponent is equal to the basek logarithm of the joint spectral radius of any set of a special class of matrices determined by the kkernel.

For our first, we introduce the notion of the eigenvalue Â¿F of a Mahler function F (z) and develop a quick test for the transcendence of F (z) over A(z), which is determined by the value of the eigenvalue Â¿F. While our first test is quick and applicable for a large class of functions, our second test, while a bit slower than our first, is universal; it depends on the rank of a certain Hankel matrix determined by the initial coefficients of F (z). We note that these are the first transcendence tests for Mahler functions of arbitrary degree. Several examples and applications are given.

[more] Â© 2015, Springer Science+Business Media New York.Let A be a finite set of dÃd matrices with integer entries and let (Formula presented.) be the maximum norm of a product of n elements of A. In this paper, we classify gaps in the growth of Pn; specifically, we prove that (Formula presented.). This has applications to the growth of regular sequences as defined by Allouche and Shallit.

In this paper, we consider the approximation of F(1/b) by algebraic numbers. In particular, we prove that F(1/b) cannot be a Liouville number. If, in addition, F(x) is regular, we show that F(1/b) is either rational or transcendental, and in the latter case that F(1/b) is an Snumber or a Tnumber in Mahler's classification of real numbers.

Using a theorem of Allouche, MendÃ¨s France, and PeyriÃ¨re and many classical results from the theory of the distribution of prime numbers, we prove that Â¿(n) is not Â¿automatic for any k > 2. This yields that S 8n=1 Â¿(n) Xn e Fp[[X]] is transcendental over Fp(X) for any prime p > 2. Similar results are proven (or reproven) for many common numbertheoretic functions, including f, Âµ, O, Â¿, Â¿, and others.
