Its primary focus is the spectral rigidity problem: Can the metric of a given Riemannian symmetric space of compact type be characterized by means of the spectrum of its Laplacian? It also addresses a question rooted in the Blaschke problem: Is a Riemannian metric on a projective space whose geodesics are all closed and of the same length isometric to the canonical metric? The authors comprehensively treat the results concerning Radon transforms and the infinitesimal versions of these two problems. Their main result implies that most Grassmannians are spectrally rigid to the first order. This is particularly important, for there are still few isospectrality results for positively curved spaces and these are the first such results for symmetric spaces of compact type of rank ?1. The authors exploit the theory of overdetermined partial differential equations and harmonic analysis on symmetric spaces to provide criteria for infinitesimal rigidity that apply to a large class of spaces. A substantial amount of basic material about Riemannian geometry, symmetric spaces, and Radon transforms is included in a clear and elegant presentation that will be useful to researchers and advanced students in differential geometry. 410 0$aAnnals of mathematics studies ;$vno. 156. 606 $aRadon transforms 606 $aGrassmann manifolds 608 $aElectronic books. 615 0$aRadon transforms. 615 0$aGrassmann manifolds. 676 $a515/.723 700 $aGasqui$b Jacques$056874 701 $aGoldschmidt$b Hubert$f1942-$056875 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910454966803321 996 $aRadon transforms and the rigidity of the grassmannians$9670617 997 $aUNINA
