These invariants can generically be determined using the spectrum of the Dirichlet problem of the Laplace operator. A natural question asks if this collection is sufficient to determine Ω up to isometry. In this paper we give a counterexample, namely, we present two nonisometric domains Ω and Ω¯ with the same collection of Marvizi–Melrose invariants. Moreover, each domain has countably many periodic orbits {Sn}n≥1 (resp. {S¯n}n⩾1) of period going to infinity such that Sn and S¯n have the same period and perimeter for each n."}],"status":"public","day":"05","quality_controlled":"1","external_id":{"arxiv":["1801.00952"]},"article_type":"original","volume":23,"language":[{"iso":"eng"}],"author":[{"last_name":"Buhovsky","first_name":"Lev","full_name":"Buhovsky, Lev"},{"orcid":"0000-0002-6051-2628","first_name":"Vadim","full_name":"Kaloshin, Vadim","last_name":"Kaloshin","id":"FE553552-CDE8-11E9-B324-C0EBE5697425"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"54-59","publication":"Regular and Chaotic Dynamics","date_created":"2020-09-17T10:43:21Z","year":"2018","article_processing_charge":"No","date_published":"2018-02-05T00:00:00Z","_id":"8426","doi":"10.1134/s1560354718010057","publication_identifier":{"issn":["1560-3547","1468-4845"]},"title":"Nonisometric domains with the same Marvizi-Melrose invariants","month":"02","oa_version":"Preprint","citation":{"chicago":"Buhovsky, Lev, and Vadim Kaloshin. “Nonisometric Domains with the Same Marvizi-Melrose Invariants.” <i>Regular and Chaotic Dynamics</i>.
