SUMMARY:Geometry and Topology Seminar
CLASS:PUBLIC
DESCRIPTION:CY MAOR\, HEBREW UNIVERSITY OF JERUSALEM\n\nStability of isomet
 ric immersions and applications\n\nAn isometric immersion f:M→N between 
 two Riemannian manifolds of the\nsame dimension is very rigid—the values
  of f(p) and Df(p) at one\npoint p∈M completely determine f. But what ca
 n be said about maps\nthat are \"almost\" isometries (in a precise sense)
 —must they be close\nto true isometries? In this talk\, I will survey th
 is question from its\norigins in the 1960s to recent developments\, and di
 scuss its\napplications to non-Euclidean elasticity\, where one seeks the 
 “most\nisometric” immersion even when exact isometric immersions do no
 t\nexist. Based on joint works with Raz Kupferman.\n\nMC 5417
