[J. Algebra 348 (2011) 446–461] provide an algorithm for finding a complete system of primitive orthogonal idempotents for CM, where M is any finite R-trivial monoid. Their method relies on a technical result stating that R-trivial monoid are equivalent to so-called weakly ordered monoids. We provide an alternative algorithm, based only on the simple observation that an R-trivial monoid may be realized by upper triangular matrices. This approach is inspired by results in the field of coupled cell network dynamical systems, where L-trivial monoids (the opposite notion) correspond to so-called feed-forward networks. We first show that our algorithm works for ZM, after which we prove that it also works for RM where R is an arbitrary ring with a known complete system of primitive orthogonal idempotents. In particular, our algorithm works if R is any field. In this respect our result constitutes a considerable generalization of the results in Berg et al. [J. Algebra 348 (2011) 446–461]. Moreover, the system of idempotents for RM is obtained from the one our algorithm yields for ZM in a straightforward manner. In other words, for any finite R-trivial monoid M our algorithm only has to be performed for ZM, after which a system of idempotents follows for any ring with a given system of idempotents."}],"extern":"1","publication":"Journal of Algebra and Its Applications","issue":"12","type":"journal_article","keyword":["Applied Mathematics","Algebra and Number Theory"],"date_created":"2022-09-06T11:37:00Z","status":"public","volume":20,"user_id":"97359","_id":"33262","publisher":"World Scientific Pub Co Pte Ltd","citation":{"mla":"Nijholt, Eddie, et al. “A New Algorithm for Computing Idempotents of ℛ-Trivial Monoids.” <i>Journal of Algebra and Its Applications</i>, vol. 20, no. 12, World Scientific Pub Co Pte Ltd, 2020, doi:<a href=\"https://doi.org/10.1142/s0219498821502273\">10.1142/s0219498821502273</a>.","apa":"Nijholt, E., Rink, B., &#38; Schwenker, S.
