SUMMARY:Pure Math Department Colloquium
CLASS:PUBLIC
DESCRIPTION:ELISABETH WERNER\, CASE WESTERN RESERVE UNIVERSITY\n\nAffine in
 variants in convex geometry\n\nIn analogy to the classical surface area\, 
 a notion of affine surface\narea (invariant under affine transformations) 
 has been defined. The\nisoperimetric inequality states that the usual surf
 ace area is\nminimized for a ball. Affine isoperimetric inequality states 
 that\naffine surface area is maximized for ellipsoids. Due to this\ninequa
 lity and its many other remarkable properties\, the affine\nsurface area f
 inds applications in many areas of mathematics and\napplied mathematics. T
 his has led to intense research in recent years\nand numerous new directio
 ns have been developed. We will discuss some\nof them and we will show how
  affine surface area is related to a\ngeometric object\, that is interesti
 ng in its own right\, the floating\nbody. \n\nMC 5501
