{"title":"Ramification filtration and differential forms","authors":"Viktor Aleksandrovich Abrashkin","doi":"10.4213/im9322e","DOIUrl":"https://doi.org/10.4213/im9322e","url":null,"abstract":"Let $L$ be a complete discrete valuation field of prime characteristic $p$ with finite residue field. Denote by $Gamma_{L}^{(v)}$ the ramification subgroups of $Gamma_{L}=operatorname{Gal}(L^{mathrm{sep}}/L)$. We consider the category $operatorname{MGamma}_{L}^{mathrm{Lie}}$ of finite $mathbb{Z}_p[Gamma_{L}]$-modules $H$, satisfying some additional (Lie)-condition on the image of $Gamma_L$ in $operatorname{Aut}_{mathbb{Z}_p}H$. In the paper it is proved that all information about the images of the groups $Gamma_L^{(v)}$ in $operatorname{Aut}_{mathbb{Z}_p}H$ can be explicitly extracted from some differential forms $widetilde{Omega} [N]$ on the Fontaine etale $phi $-module $M(H)$ associated with $H$. The forms $widetilde{Omega}[N]$ are completely determined by a canonical connection $nabla $ on $M(H)$. In the case of fields $L$ of mixed characteristic, which contain a primitive $p$th root of unity, we show that a similar problem for $mathbb{F}_p[Gamma_L]$-modules also admits a solution. In this case we use the field-of-norms functor to construct the corresponding $phi $-module together with the action of the Galois group of a cyclic extension $L_1$ of $L$ of degree $p$. Then our solution involves the characteristic $p$ part (provided by the field-of-norms functor) and the condition for a \"good\" lift of a generator of $operatorname{Gal}(L_1/L)$. Apart from the above differential forms the statement of this condition uses the power series coming from the $p$-adic period of the formal group $mathbb{G}_m$.","PeriodicalId":54910,"journal":{"name":"Izvestiya Mathematics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under certain general assumptions, existence and regularity of a mild solution to the dynamical system are established by employing a surjectivity result for weakly-weakly upper semicontinuous multivalued mappings, and a feedback iterative technique together with a temporally semi-discrete approach through the backward Euler difference scheme with quasi-uniform time-steps. To illustrate the applicability of the abstract results, we consider a nonstationary and incompressible Navier-Stokes system supplemented by a fractional reaction-diffusion equation, which is studied as a fractional hemivariational inequality.","PeriodicalId":54910,"journal":{"name":"Izvestiya Mathematics","volume":"8 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136079305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
