Narrow operators are those operators defined on function spaces that are "small" at {-1,0,1}-valued functions, e.g. compact operators are narrow. The original motivation to consider such operators came from theory of embeddings of Banach spaces, but since then they were also applied to the study of the Daugavet property and to other geometrical problems of functional analysis. The question of when a sum of two narrow operators is narrow, has led to deep developments of the theory of narrow operators, including an extension of the notion to vector lattices and investigations of connections to regular operators. Narrow operators were a subject of numerous investigations during the last 30 years. This monograph provides a comprehensive presentation putting them in context of modern theory. It gives an in depth systematic exposition of concepts related to and influenced by narrow operators, starting from basic results and building up to most recent developments. The authors include a complete bibliography and many attractive open problems. 410 3$aDe Gruyter Studies in Mathematics 606 $aNarrow operators 606 $aRiesz spaces 606 $aFunction spaces 608 $aElectronic books. 615 0$aNarrow operators. 615 0$aRiesz spaces. 615 0$aFunction spaces. 676 $a515/.73 700 $aPopov$b Mykhai?lo Mykhai?lovych$01040328 701 $aRandrianantoanina$b Beata$0518410 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910453054303321 996 $aNarrow operators on function spaces and vector lattices$92463087 997 $aUNINA
