On non-formality of homogeneous spaces

One of the interesting and important rational homotopy properties of a topological space $X$ is that of {\em formality}. In this paper we prove the non-formality property of some family homogeneous spaces.

A note on the no-three-in-line problem on a torus

In this paper we show that at most $2 \gcd(m,n)$ points can be placed with no three in a line on an $m\times n$ discrete torus. In the situation when $\gcd(m,n)$ is a prime, we completely solve the problem.
