Some useful classes of algebras --BackmatterThe category of all modules over a general associative ring is too complex to admit any reasonable classification. Thus, unless the ring is of finite representation type, one must limit attempts at classification to some restricted subcategories of modules. The wild character of the category of all modules, or of one of its subcategories C is often indicated by the presence of a realization theorem, that is, by the fact that any reasonable algebra is isomorphic to the endomorphism algebra of a module from C. This results in the existence of pathological direct sum decompositions and these are generally viewed as obstacles to the classification. Realization theorems have thus become important indicators of the non-classification theory of modules. In order to overcome this problem, approximation theory of modules has been developed over the past few decades. The idea here is to select suitable subcategories C whose modules can be classified, and then to approximate arbitrary modules by ones from C. These approximations are neither unique nor functorial in general, but there is always a rich supply available appropriate to the requirements of various particular applications. Thus approximation theory has developed into an important part of the classification theory of modules. In this monograph the two methods are brought together. First the approximation theory of modules is developed and some of its recent applications, notably to infinite dimensional tilting theory, are presented. Then some prediction principles from set theory are introduced and these become the principal tools in the establishment of appropriate realization theorems. The monograph starts from basic facts and gradually develops the theory towards its present frontiers. It is suitable both for graduate students interested in algebra and for experts in module and representation theory.Gruyter expositions in mathematics ;41.Modules (Algebra)Moduli theoryApproximation theoryModules (Algebra)Moduli theory.Approximation theory.512/.42510sdnbSK 150rvkSK 230rvkSK 820rvkGöbel R(Rüdiger),1940-60070Trlifaj Jan1925934MiAaPQMiAaPQMiAaPQBOOK9911107078803321Approximations and endomorphism algebras of modules4673607UNINA04549nam 2200697Ia 450 991109280700332120251117093034.00-262-30507-01-283-90641-40-262-30599-2ebc3339554(CKB)2670000000319473(EBL)3339554(SSID)ssj0000782703(PQKBManifestationID)12347027(PQKBTitleCode)TC0000782703(PQKBWorkID)10751831(PQKB)10824773(MiAaPQ)EBC3339554(OCoLC)961604092(OCoLC)822894364(OCoLC)826443238(OCoLC)962707495(OCoLC)1035786344(OCoLC)1055342490(OCoLC)1066559722(OCoLC)1081212980(OCoLC-P)961604092(MaCbMITP)9517(Au-PeEL)EBL3339554(CaPaEBR)ebr10640076(CaONFJC)MIL421891(OCoLC)822894364(EXLCZ)99267000000031947320120503d2013 uy 0engurcn|||||||||txtccrBanking the world empirical foundations of financial inclusion /edited by Robert Cull, Asli Demirguc-Kunt, and Jonathan Morduch1st ed.Cambridge, Mass.

VI Conclusion; 15 Ten Research Questions; Contributors; IndexAbout 2.5 billion adults, just over half the world's adult population, lack bank accounts. If we are to realize the goal of extending banking and other financial services to this vast "unbanked" population, we need to consider not only such product innovations as microfinance and mobile banking but also issues of data accuracy, impact assessment, risk mitigation, technology adaptation, financial literacy, and local context. In Banking the World, experts take up these topics, reporting on new research that will guide both policy makers and scholars in a broader push to extend financial markets. The contributors consider such topics as the complexity of surveying people about their use of financial services; evidence of the impact of financial services on income; the occasional negative effects of financial services on poor households, including disincentives to work and overindebtedness; and tools for improving access such as nontraditional credit scores, financial incentives for banking, and identification technologies that can dramatically reduce loan default rates.FinanceDeveloping countriesBanks and bankingDeveloping countriesFinancial institutionsDeveloping countriesFinanceBanks and bankingFinancial institutions332.109172/4Cull Robert J140582Demirguc-Kunt Asl1961-1621499Morduch Jonathan612718MiAaPQMiAaPQMiAaPQBOOK9911092807003321Banking the world4672110UNINA
