This book provides a detailed exposition of the basic techniques of Carleman Inequalities, driven by applications to various questions of unique continuation. Beginning with an elementary introduction to the topic, including examples accessible to readers without prior knowledge of advanced mathematics, the book's first five chapters contain a thorough exposition of the most classical results, such as Calderón's and Hörmander's theorems. Later chapters explore a selection of results of the last four decades around the themes of continuation for elliptic equations, with the Jerison-Kenig estimates for strong unique continuation, counterexamples to Cauchy uniqueness of Cohen and Alinhac & Baouendi, operators with partially analytic coefficients with intermediate results between Holmgren's and Hörmander's uniqueness theorems, Wolff's modification of Carleman's method, conditional pseudo-convexity, and more. With examples and special cases motivating the general theory, as well as appendices on mathematical background, this monograph provides an accessible, self-contained basic reference on the subject, including a selection of the developments of the past thirty years in unique continuation.Grundlehren der mathematischen Wissenschaften, A Series of Comprehensive Studies in Mathematics,0072-7830 ;353Operator theoryPartial differential equationsOperator Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/M12139Partial Differential Equationshttps://scigraph.springernature.com/ontologies/product-market-codes/M12155Operator theory.Partial differential equations.Operator Theory.Partial Differential Equations.515.26515.26Lerner Nicolasauthttp://id.loc.gov/vocabulary/relators/aut61544BOOK9910338246003321Carleman Inequalities1732393UNINA
