*"Affine vs. Euclidean Isoperimetric Inequalities"*

**

/_Abstract:_///The equivalence of the classical Euclidean isoperimetric 
inequality and the sharp/L_1 /Sobolev inequality is a beautiful example 
of the interplay between geometric and analytic inequalities. This 
remarkable link has been amplifiedby the recent work on /affine/ 
isoperimetric and analytic inequalities. An /affine/ /isoperimetric 
inequality/ is an inequality between geometric functionals which are 
invariant under volume preserving linear transformations. In contrast to 
thecommon misbelief that Euclidean inequalities (that is, inequalities 
for functionals invariant under rigid motions only) are stronger than 
affine inequalities, it has become apparent over the last decades that 
affine isoperimetric inequalities arethe most powerful inequalities of 
(convex) geometric analysis.In this talk we discuss, in particular, one 
of the most important examples of an affine isoperimetric 
inequality:/Petty's/ /projection inequality/. It states that among 
compact, convex sets of given volume, the ones whose polar projection 
bodies have maximal volume are precisely the ellipsoids. We will give an 
overview ofthe impact over the last decade of this inequality, it's 
analytic version (the /affine Zhang-Sobolev inequality/), and their /L_p 
/ generalizations by Lutwak-Yang-Zhang and Haberl and myself. We will 
also shed new light on the special role of Petty's projection inequality 
in affine geometric analysis by exploiting the fascinating connections 
between the theory of isoperimetric inequalities and the theory of 
valuations which were first discovered by Ludwig.
