We give an extension of the Fekete's Subadditive Lemma for a set of submultiplicative functionals on countable product of compact spaces. Our method can be considered as an unfolding of the ideas [1]Theorem 3.1 and our main result is an extension of the symbolic dynamics results of [4].

{\displaystyle a_{n+m}\geq a_{n}+a_{m}.} (The limit then may be positive infinity: consider the sequence a n = log ⁡ n ! {\displaystyle a_{n}=\log n!} .) 2011-12-01 · Fekete’s lemma is a very important lemma, which is used to prove that a certain limit exists. The only thing to be checked is the super-additivity property of the function of interest. Let’s be more exact.

I, Indag.Math., 13 (1951), 374–382 top We show that if a real n × n non-singular matrix (n ≥ m) has all its minors of order m-1 non-negative and has all its minors of order m which come from consecutive rows non-negative, then all m th order minors are non-negative, which may be considered an extension of Fekete’s lemma.

Fekete's lemma is a well known combinatorial result pertaining to number sequences and shows the existence of limits of superadditive sequences.

一つ前の記事と似てるような似てないような、なので書いておくを数列とする。任意のに対して (優加法性) を満たすならば、 を満たす 直感的には、とりあえずが(どこかから)非減少列であることを示せてしまえればよさそうに見える。 しかし、この方針では厳しい。たとえば、 のようにと Let f : {1,2,} → [0,+∞). Fekete’s lemma[2, 3, 8] states that, if f(n+k) ≤ f(n)+f(k) for all n and k, then lim n→∞ f(n) n (1) exists, and equals inf n≥1 f(n)/n.

We give an extension of the Fekete's Subadditive Lemma for a set of submultiplicative functionals on countable product of compact spaces. Our method can be

This in particular implies that , i.e. the sequence cannot grow faster than linearly, but we actually know more thanks to Fekete: Theorem (Fekete).

Fekete's Subadditive Lemma: For every subadditive sequence {} = ∞, the limit → ∞ exists and is equal to the infimum. (The limit may be − ∞ {\displaystyle -\infty } .) The analogue of Fekete's lemma holds for superadditive sequences as well, that is: a n + m ≥ a n + a m . {\displaystyle a_{n+m}\geq a_{n}+a_{m}.} (The limit then may be positive infinity: consider the sequence a n = log ⁡ n ! {\displaystyle a_{n}=\log n!} .)

It has thus become essential for workers in many We show that if a real n × n non-singular matrix (n ≥ m) has all its minors of order m − 1 non-negative and has all its minors of order m which come from consecutive rows non-negative, then all mth order minors are non-negative, which may be considered an extension of Fekete's lemma.

Fekete's lemma is a well known combinatorial result pertaining to number sequences and shows the existence of limits of superadditive sequences. In this paper we analyze Fekete's lemma with respect to effective convergence and computability. We show that Fekete's lemma exhibits no constructive derivation.
