We refer in particular to (Lahav <jats:italic>et al<\/jats:italic> 2022 <jats:italic>Sci. Rep.<\/jats:italic>\n                  <jats:bold>12<\/jats:bold> 2508), where the theory was illustrated by means of a skew product system, coupling two logistic maps. In this case, we show that the topological synchronisation could be easily explained as the birth of an attractor for increasing values of the coupling strength and the mutual convergence of two marginal empirical measures. Numerical computations based on a careful analysis of the Lyapunov exponents suggest that the attractor supports an absolutely continuous physical measure (acpm). We finally show that for some unimodal maps such acpm exhibit a multifractal structure.<\/jats:p>","DOI":"10.1088\/1361-6544\/acd42f","type":"journal-article","created":{"date-parts":[[2023,5,30]],"date-time":"2023-05-30T07:06:12Z","timestamp":1685430372000},"page":"3603-3621","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Topological synchronisation or a simple attractor?"],"prefix":"10.1088","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8960-7279","authenticated-orcid":true,"given":"Th\u00e9ophile","family":"Caby","sequence":"first","affiliation":[]},{"given":"Michele","family":"Gianfelice","sequence":"additional","affiliation":[]},{"given":"Beno\u00eet","family":"Saussol","sequence":"additional","affiliation":[]},{"given":"Sandro","family":"Vaienti","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2023,5,30]]},"reference":[{"key":"nonacd42fbib1","doi-asserted-by":"publisher","first-page":"2508","DOI":"10.1038\/s41598-022-06262-z","article-title":"Topological synchronization of chaotic systems","volume":"12","author":"Lahav","year":"2022","journal-title":"Sci.
