Koszul duality is a fundamental phenomenon in homological algebra and related areas of mathematics, such as algebraic topology, algebraic geometry, and representation theory. Koszul duality is a popular subject of contemporary research. This book, written by one of the world's leading experts in the area, includes the homogeneous and nonhomogeneous quadratic duality theory over a nonsemisimple, noncommutative base ring, the Poincare?Birkhoff?Witt theorem generalized to this context, and triangulated equivalences between suitable exotic derived categories of modules, curved DG comodules, and curved DG contramodules. The thematic example, meaning the classical duality between the ring of differential operators and the de Rham DG algebra of differential forms, involves some of the most important objects of study in the contemporary algebraic and differential geometry. For the first time in the history of Koszul duality the derived D-\Omega duality is included into a general framework. Examples highly relevant for algebraic and differential geometry are discussed in detail. 410 0$aFrontiers in Mathematics,$x1660-8054 606 $aAlgebra, Homological 606 $aCategory Theory, Homological Algebra 606 $aTeoria de la dualitat (Matemàtica)$2thub 608 $aLlibres electrònics$2thub 615 0$aAlgebra, Homological. 615 14$aCategory Theory, Homological Algebra. 615 7$aTeoria de la dualitat (Matemàtica) 676 $a515.782 676 $a512.46 700 $aPositselski$b Leonid$f1973-$0499475 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9910544846603321 996 $aRelative Nonhomogeneous Koszul Duality$92644851 997 $aUNINA
