Affine invariant

WebEven though this notion is intriguing in its simplicity, little is known about affine invariant points. At the same time, these are fundamental invariants of convex sets. They are, for instance, useful to characterize properties of symmetry or of non-symmetry of convex bodies (e.g., [13] and [14]). WebThe following invariants of "pointed" convex bodies (i.e., pairs consisting of a convex body and a distinguished point in its interior) roughly measure how many of its linear images fit between the ... both of these invariant yield affine invariants. Basic properties of the invariant $\rho$. 1.1 $\rho((K,0), 1) = 0$ and $\rho((K,0), \lambda) ...
