Generalization of Chebyshev Inequality (N.Dergiades G.Tsintsifas)
In our generalization we have found intermediate terms between the two parts of the Chebyshev inequality
An interesting theorem in Topology
We prove an interesting theorem in Topology similar to the Helly type theorem in Convexity.
Two conjectures for convex sets
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.
