Beginning with an overview of fundamentals, definitions, and conventions, this book quickly moves forward to discuss the Reshetnyak gluing theorem and applies it to the billiards problems. The Hadamard?Cartan globalization theorem is explored and applied to construct exotic aspherical manifolds. 410 0$aSpringerBriefs in Mathematics,$x2191-8198 606 $aDifferential geometry 606 $aGroup theory 606 $aDifferential Geometry$3https://scigraph.springernature.com/ontologies/product-market-codes/M21022 606 $aGroup Theory and Generalizations$3https://scigraph.springernature.com/ontologies/product-market-codes/M11078 615 0$aDifferential geometry. 615 0$aGroup theory. 615 14$aDifferential Geometry. 615 24$aGroup Theory and Generalizations. 676 $a513.8 676 $a516.373 700 $aAlexander$b Stephanie$4aut$4http://id.loc.gov/vocabulary/relators/aut$0780987 702 $aKapovitch$b Vitali$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aPetrunin$b Anton$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910338247603321 996 $aAn Invitation to Alexandrov Geometry$92510889 997 $aUNINA
