There is a vast literature on establishing Arnold diffusion for such systems. In this work, we consider the case when an additional, dissipative perturbation is added to the rotator-pendulum system with coupling. Therefore, the system obtained is not symplectic but conformally symplectic. We provide explicit conditions on the dissipation parameter, so that the resulting system still exhibits energy growth. The fact that Arnold diffusion may play a role in systems with small dissipation was conjectured by Chirikov. In this work, the coupling is carefully chosen, but the mechanism we present can be adapted to general couplings, and we will deal with the general case in future work.<\/jats:p>","DOI":"10.1137\/22m1525508","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T04:40:43Z","timestamp":1691124043000},"page":"1983-2023","source":"Crossref","is-referenced-by-count":3,"title":["Arnold Diffusion in a Model of Dissipative System"],"prefix":"10.1137","volume":"22","author":[{"given":"Samuel W.","family":"Akingbade","sequence":"first","affiliation":[{"name":"Department of Mathematical Sciences, Yeshiva University, New York, NY 10016 USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4248-9890","authenticated-orcid":true,"given":"Marian","family":"Gidea","sequence":"additional","affiliation":[{"name":"Department of Mathematical Sciences, Yeshiva University, New York, NY 10016 USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tere","family":"M-Seara","sequence":"additional","affiliation":[{"name":"Departament de Matem\u00e0tiques and IMTECH, Universitat Polit\u00e8cnica de Catalunya (UPC), Diagonal 647, 08028 Barcelona, Spain, and Centre de Recerca Matem\u00e0tica, Barcelona, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2023,8,4]]},"reference":[{"key":"ref1","first-page":"581","volume":"5","author":"Arnold V.
