This book represents a first attempt to give a systematic account on the subject. Hadamard spaces are complete geodesic spaces of nonpositive curvature. They include Hilbert spaces, Hadamard manifolds, Euclidean buildings and many other important spaces. While the role of Hadamard spaces in geometry and geometric group theory has been studied for a long time, first analytical results appeared as late as in the 1990's. Remarkably, it turns out that Hadamard spaces are appropriate for the theory of convex sets and convex functions outside of linear spaces. Since convexity underpins a large number of results in the geometry of Hadamard spaces, we believe that its systematic study is of substantial interest. Optimization methods then address various computational issues and provide us with approximation algorithms which may be useful in sciences and engineering. We present a detailed description of such an application to computational phylogenetics. The book is primarily aimed at both graduate students and researchers in analysis and optimization, but it is accessible to advanced undergraduate students as well. 410 0$aDe Gruyter series in nonlinear analysis and applications ;$vVolume 22. 606 $aMetric spaces 606 $aG-spaces 606 $aHadamard matrices 610 $aConvex analysis. 610 $aConvex optimization. 610 $aGeodesic convexity. 610 $aHadamard space. 610 $aMetric geometry. 610 $aNonpositive curvature. 615 0$aMetric spaces. 615 0$aG-spaces. 615 0$aHadamard matrices. 676 $a511/.6 686 $aSK 870$2rvk 700 $aBaca?k$b Miroslav$01524232 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910788824003321 996 $aConvex analysis and optimization in Hadamard spaces$93764897 997 $aUNINA
