Abstract: | The covariogram of a convex body K provides the volumes of theintersections of K with all its possible translates. Matheronconjectured in 1986 that this information determines K amongall convex bodies, up to certain known ambiguities. It is provedthat this is the case if K R2 is not C1, or it is not strictlyconvex, or its boundary contains two arbitrarily small C2 openportions on opposite sides. Examples are alsoconstructed that show that this conjecture is false in Rn forany n 4. |
