Query: Equilibrium and equivariant triangulations of some small covers with
  minimum number of vertices   Small covers were introduced by Davis and Januszkiewicz in 1991. We introduce
the notion of equilibrium triangulations for small covers. We study equilibrium
and vertex minimal $\mathbb{Z}_2^2$-equivariant triangulations of
$2$-dimensional small covers. We discuss vertex minimal equilibrium
triangulations of $\mathbb{RP}^3 \# \mathbb{RP}^3$, $S^1 \times \mathbb{RP}^2$
and a nontrivial $S^1$ bundle over $\mathbb{RP}^2$. We construct some nice
equilibrium triangulations of the real projective space $\mathbb{RP}^n$ with
$2^n +n+1$ vertices. The main tool is the theory of small covers.
