Indices for the Exceptional Bruhat-Tits Buildings -- $tBibliography -- $tIndex 330 $aDescent in Buildings begins with the resolution of a major open question about the local structure of Bruhat-Tits buildings. The authors then put their algebraic solution into a geometric context by developing a general fixed point theory for groups acting on buildings of arbitrary type, giving necessary and sufficient conditions for the residues fixed by a group to form a kind of subbuilding or "form" of the original building. At the center of this theory is the notion of a Tits index, a combinatorial version of the notion of an index in the relative theory of algebraic groups. These results are combined at the end to show that every exceptional Bruhat-Tits building arises as a form of a "residually pseudo-split" Bruhat-Tits building. The book concludes with a display of the Tits indices associated with each of these exceptional forms.This is the third and final volume of a trilogy that began with Richard Weiss' The Structure of Spherical Buildings and The Structure of Affine Buildings. 410 0$aAnnals of mathematics studies ;$v190. 606 $aBuildings (Group theory) 606 $aCombinatorial geometry 608 $aElectronic books. 615 0$aBuildings (Group theory) 615 0$aCombinatorial geometry. 676 $a516/.13 700 $aMu?hlherr$b Bernhard Matthias$01030595 702 $aPetersson$b Holger P.$f1939- 702 $aWeiss$b Richard M$g(Richard Mark),$f1946- 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910461572703321 996 $aDescent in buildings$92447559 997 $aUNINA
