Whilst basic\u0000analytic properties of the $L$-functions can be difficult to understand, recent\u0000research programs have shown that automorphic $L$-values are susceptible to\u0000study via algebraic methods linking them to Selmer groups. Iwasawa theory,\u0000pioneered first by Iwasawa in the 1960s and later Mazur and Wiles provides an\u0000algebraic recipe to obtain a $p$-adic analogue of the $L$-function. In this\u0000work we aim to adapt Iwasawa theory to a new context of representations of the\u0000unitary group GU(2,1) at primes inert in the respective imaginary quadratic\u0000field. This requires a novel approach using the Schneider--Venjakob regulator\u0000map, working over locally analytic distribution algebras. Subsequently, we show\u0000vanishing of some Bloch--Kato Selmer groups when a certain $p$-adic\u0000distribution is non-vanishing. These results verify cases of the Bloch--Kato\u0000conjecture for GU(2,1) at inert primes in rank 0.","PeriodicalId":501136,"journal":{"name":"arXiv - MATH - Rings and Algebras","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
