Universitext,0172-59393-319-56220-7 Includes bibliographical references and index.Invitation to the Trip -- Hyperplane Arrangements and their Combinatorics -- Orlik–Solomon Algebras and de Rham Cohomology -- On the Topology of the Complement M(A) -- Milnor Fibers and Local Systems -- Characteristic Varieties and Resonance Varieties -- Logarithmic Connections and Mixed Hodge Structures -- Free Arrangements and de Rham Cohomology of Milnor Fibers.This textbook provides an accessible introduction to the rich and beautiful area of hyperplane arrangement theory, where discrete mathematics, in the form of combinatorics and arithmetic, meets continuous mathematics, in the form of the topology and Hodge theory of complex algebraic varieties. The topics discussed in this book range from elementary combinatorics and discrete geometry to more advanced material on mixed Hodge structures, logarithmic connections and Milnor fibrations. The author covers a lot of ground in a relatively short amount of space, with a focus on defining concepts carefully and giving proofs of theorems in detail where needed. Including a number of surprising results and tantalizing open problems, this timely book also serves to acquaint the reader with the rapidly expanding literature on the subject. Hyperplane Arrangements will be particularly useful to graduate students and researchers who are interested in algebraic geometry or algebraic topology. The book contains numerous exercises at the end of each chapter, making it suitable for courses as well as self-study.Universitext,0172-5939Geometry, AlgebraicCommutative algebraCommutative ringsFunctions of complex variablesAlgorithmsGeometry, ProjectiveCombinatorial analysisAlgebraic Geometryhttps://scigraph.springernature.com/ontologies/product-market-codes/M11019Commutative Rings and Algebrashttps://scigraph.springernature.com/ontologies/product-market-codes/M11043Several Complex Variables and Analytic Spaceshttps://scigraph.springernature.com/ontologies/product-market-codes/M12198Algorithmshttps://scigraph.springernature.com/ontologies/product-market-codes/M14018Projective Geometryhttps://scigraph.springernature.com/ontologies/product-market-codes/M21050Combinatoricshttps://scigraph.springernature.com/ontologies/product-market-codes/M29010Geometry, Algebraic.Commutative algebra.Commutative rings.Functions of complex variables.Algorithms.Geometry, Projective.Combinatorial analysis.Algebraic Geometry.Commutative Rings and Algebras.Several Complex Variables and Analytic Spaces.Algorithms.Projective Geometry.Combinatorics.516.35Dimca Alexandruauthttp://id.loc.gov/vocabulary/relators/aut59495MiAaPQMiAaPQMiAaPQBOOK9910254281403321Hyperplane arrangements1560433UNINA
