This is a paper about cutting numbers

The projections on the coordinate planes of a convex body. The Loomis-Whitney inequality.

In our generalization we have found intermediate terms between the two parts of the Chebyshev inequality

We prove an interesting theorem in Topology similar to the Helly type theorem in Convexity.

R.J.Gardner, S.Kwapien and D.P.Laurie working on a conjecture of B.Grunbaum, reached two elegant conjectures including inequalities about ovals. Here is an interesting solution.
