Thanks! 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. 2013-01-13 · Lemma 1 (Fekete’s lemma) If satisfies for all then . Proof: The inequality is immediate from the definition of , so it suffices to prove for each . Fix such a and set .

2020-10-19 · Abstract: 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. Fekete's (subadditive) lemma takes its name from a 1923 paper by the Hungarian mathematician Michael Fekete [1]. A historical overview and references to (a couple of) generalizations and applications of the result are found in Steele's book on probability and combinatorial optimization [2, Section 1.10], where a special mention is made to the work The idea is to give an introduction to the subject, following Hille’s and Lind and Marcus’s textbooks, and stating an important theorem by the Hungarian mathematician Mihály Fekete; then, discuss some extensions to the case of many variables and their implications in the theory of cellular automata, referring to two of my papers from 2008, one of them with Tommaso Toffoli and Patrizia Mentrasti. 2014-03-31 · Abstract: 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].

If there is a msuch that am=-∞, then, by subadditivity, we have an=-∞for all n>m.

and stating an important theorem by the Hungarian mathematician Mihály Fekete; Fekete's lemma shows the existence of limits in subadditive sequences. This lemma, and generalisations of it, also have been used to prove the existence of One can show (e.g., by using Fekete's lemma) that the limit always exists and can be equiv- alently written as. Θ(G) = sup k α1/k(Gk).

By a lemma of Fekete [7, p. 5583, every sequence with the property (P) is also totally positive in the following strict sense: all the finite minors of (3).
