August 26, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- New research on Information Technology is the subject of a report. According to news originating from Turku, Finland, by VerticalNews correspondents, research stated, "We study the freeness problem for matrix semigroups."

Our news journalists obtained a quote from the research from the University of Turku, "We show that the freeness problem is decidable for upper-triangular 2 x 2 matrices with rational entries when the products are restricted to certain bounded languages."

According to the news editors, the research concluded: "We also show that this problem becomes undecidable for sufficiently large matrices."
