A note on "A combinatorial proof of associativity of Ore extensions"
(2014) In Discrete Mathematics 315. p.156-157- Abstract
- Nystedt recently gave a combinatorial proof of the fact that Ore extensions are associative. As part of it he proves that two sets of strings are identical, using a counting argument. We show that the equality of the sets can be proven directly. (C) 2013 Elsevier B.V. All rights reserved.
