Study Data from University of Montpellier Update Understanding of Information Technology

June 24, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Data detailed on Information Technology have been presented. According to news reporting from Montpellier, France, by VerticalNews editors, the research stated, "An infinite square-free word w over the alphabet Sigma(3) = {0, 1, 2} is said to have a k-stem sigma if vertical bar sigma vertical bar = k and w = sigma w(1)w(2) ... where for each i, there exists a permutation pi(i) of Sigma(3) which extended to a morphism gives w(i) = pi(i) (sigma). Harju proved that there exists an infinite k-stem word for k = 1, 2, 3, 9 and 13

The news correspondents obtained a quote from the research from the University of Montpellier, "He asked whether k-stem words exist for each k>= 20. We give a positive answer to this question."

According to the news reporters, the research concluded: "Currie has found another construction that answers Harju's question."
