Recent de- velopmentsinlow-dimensionaltopology,algebraicgeometry,symplecticgeometry, complexanalysis,andtropicalgeometryaresorichwithimpressiveexamplesthat any attempt to reflect a major portion of them in a single volume would be too ambitious. Forexample,recentexcitingprogressinlow-dimensionaltopologyandgeometry would have been unthinkable without powerful techniques from analysis; new achievementsintopologyandsymplecticgeometryhavebeeninfluencingcomplex analysis; methodsof tropical geometryare being used in algebraic geometry,sta- tisticalphysics,andcomplexanalysis;differentialequationscomingfromcomplex analysishaveapplicationsinalgebraicgeometry. The variety of topics presented by leading experts in this volume should nonetheless give some sense of recent developments in these fields and their interactionswithoneanother. A Marcus Wallenberg Symposium on Perspectives in Analysis, Geometry,and TopologywasheldatStockholmUniversityinMay2008.Thechoiceofsubjectsfor thissymposiumandthisvolumewasmotivatedbytheworkandthemathematical interests of Oleg Viro, to whom the symposium and this collection are dedicated. As a mathematician with broad education and interests, Viro has a deep feeling for the unity of mathematics. Viro is famous for fundamental results in several areas of geometry and topology. As a professor at Uppsala University, Viro has madeinvaluablecontributionstoSwedishresearchbycomplementingthecountry’s longstandingtraditioninanalysiswithhisownrenownedexpertiseingeometryand topology. ix
