In the particular case of q-difference equations, authors have introduced several different Galois theories. In this memoir we consider an arithmetic approach to the Galois theory of q-difference equations and we use it to establish an arithmetical description of some of the Galois groups attached to q-difference systems"--$cProvided by publisher. 410 0$aMemoirs of the American Mathematical Society 606 $aGalois theory 606 $aDifference equations 606 $aDifference and functional equations -- Difference equations -- Difference equations, scaling ($q$-differences)$2msc 606 $aField theory and polynomials -- Differential and difference algebra -- Difference algebra$2msc 615 0$aGalois theory. 615 0$aDifference equations. 615 7$aDifference and functional equations -- Difference equations -- Difference equations, scaling ($q$-differences). 615 7$aField theory and polynomials -- Differential and difference algebra -- Difference algebra. 676 $a515/.625 676 $a512.32 686 $a39A13$a12H10$2msc 700 $aVizio$b Lucia Di$01799920 701 $aHardouin$b Charlotte$01799921 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910955333303321 996 $aIntrinsic Approach to Galois Theory of$94344351 997 $aUNINA LEADER 02631nam 2200529 u 450 001 9910510400103321 005 20230621140306.0 010 $a2-919448-44-7 024 7 $a10.4000/books.esb.3850 035 $a(CKB)5100000000115655 035 $a(FrMaCLE)OB-esb-3850 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/85346 035 $a(PPN)259393002 035 $a(oapen)doab85346 035 $a(EXLCZ)995100000000115655 100 $a20220502d2021 uy 0 101 0 $afre 135 $auu||||||m|||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aCorrespondances de femmes et diplomatie$e(Espagne, France, Italie, IXe-XVe s.) 210 $aParis$ce-Spania Books$d2021 210 1$ce-Spania Books$aParis$d2021 215 $a1 online resource 225 1 $aStudies$v10 330 $aCet ouvrage recueille les communications présentées lors du troisième colloque du projet de recherche MISSIVA, qui s?est tenu les 28, 29 et 30 octobre 2019 à l?École Française de Rome et à l?Istituto Storico Italiano per il Medioevo de Rome. Le propos de cette rencontre était d?approfondir l?analyse du rôle politique des femmes du Moyen Âge à travers leur correspondance pour voir si une diplomatie au féminin avait existé et déterminer, le cas échéant, ses particularités.Les études proposées permettent d?observer, sur une longue période ? du IXe au XVe siècle ? et dans plusieurs aires géographiques, un large éventail d?exemples qui témoigne du rôle parfois déterminant des lettres de femmes dans le jeu diplomatique. Instrument de médiation, de négociation et de communication, la correspondance des femmes met en lumière les différents champs dans lesquels elles interviennent, selon leur fonction et leur position sociale ou familiale, ainsi que les stratégies politiques et discursives qu?elles mettent en ?uvre. 606 $aGender studies, gender groups$2bicssc 610 $aMiddle Ages 610 $aSpain 610 $aFrance 610 $aItaly 610 $awomen 610 $afeminine diplomacy 610 $awomen?s correspondence 610 $awomen?s letters 610 $aMISSIVA 615 7$aGender studies, gender groups 700 $aLazzarini$b Isabella$4edt$0258977 702 $aLazzarini$b Isabella 702 $aNieto Soria$b Jose?
