The central notion is that of an "almost ring". Almost rings are the commutative unitary monoids in a tensor category obtained as a quotient V-Mod/S of the category V-Mod of modules over a fixed ring V; the subcategory S consists of all modules annihilated by a fixed ideal m of V, satisfying certain natural conditions. The reader is assumed to be familiar with general categorical notions, some basic commutative algebra and some advanced homological algebra (derived categories, simplicial methods). Apart from these general prerequisites, the text is as self-contained as possible. One novel feature of the book - compared with Faltings' earlier treatment - is the systematic exploitation of the cotangent complex, especially for the study of deformations of almost algebras. 410 0$aLecture Notes in Mathematics,$x0075-8434 ;$v1800 606 $aAlgebra 606 $aCommutative algebra 606 $aCommutative rings 606 $aAlgebraic geometry 606 $aCategory theory (Mathematics) 606 $aHomological algebra 606 $aField theory (Physics) 606 $aAlgebra$3https://scigraph.springernature.com/ontologies/product-market-codes/M11000 606 $aCommutative Rings and Algebras$3https://scigraph.springernature.com/ontologies/product-market-codes/M11043 606 $aAlgebraic Geometry$3https://scigraph.springernature.com/ontologies/product-market-codes/M11019 606 $aCategory Theory, Homological Algebra$3https://scigraph.springernature.com/ontologies/product-market-codes/M11035 606 $aField Theory and Polynomials$3https://scigraph.springernature.com/ontologies/product-market-codes/M11051 615 0$aAlgebra. 615 0$aCommutative algebra. 615 0$aCommutative rings. 615 0$aAlgebraic geometry. 615 0$aCategory theory (Mathematics). 615 0$aHomological algebra. 615 0$aField theory (Physics). 615 14$aAlgebra. 615 24$aCommutative Rings and Algebras. 615 24$aAlgebraic Geometry. 615 24$aCategory Theory, Homological Algebra. 615 24$aField Theory and Polynomials. 676 $a510 700 $aGabber$b Ofer$4aut$4http://id.loc.gov/vocabulary/relators/aut$0149498 702 $aRamero$b Lorenzo$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910144601603321 996 $aAlmost Ring Theory$92543722 997 $aUNINA
