<description>
<string language="fre"><![CDATA[In the 
talk I would like to discuss some  statements and questions about convex
subsets and convex hulls in generic Riemannian manifolds of dimension 
at least 3. The statements, obtained jointly with Anton Petrunin,  are 
elementary but somewhat  surprising for the Euclidean intuition. For 
instance, the convex hull of any finite non-collinearset  turns out to be  either   the whole manifold or non-closed.]]></string></description>
