Model reduction techniques are among the core tools for studying dynamical systems models, they allow to reduce the study of a model to a simpler one. In this poster, we present an algorithm for computing exact nonlinear reductions, that is, a set of new rational function macro-variables which satisfy a self-consistent ODE system with the dynamics defined by algebraic functions. We report reductions found by the algorithm in models from the literature.<\/jats:p>","DOI":"10.1145\/3572867.3572869","type":"journal-article","created":{"date-parts":[[2022,11,24]],"date-time":"2022-11-24T00:37:32Z","timestamp":1669250252000},"page":"25-31","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Computing exact nonlinear reductions of dynamical models"],"prefix":"10.1145","volume":"56","author":[{"given":"Antonio","family":"Jim\u00e9nez-Pastor","sequence":"first","affiliation":[{"name":"Institute Polytechnique de Paris, Palaiseau, France"}]},{"given":"Gleb","family":"Pogudin","sequence":"additional","affiliation":[{"name":"Institute Polytechnique de Paris, Palaiseau, France"}]}],"member":"320","published-online":{"date-parts":[[2022,11,23]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Recurrence and topology","author":"Alongi J.
