Around right-angled hyperbolic polytopes

Аннотация: We will consider a class of polytopes which can be realized in a hyperbolic space with all dihedral angled equal to $\pi/2$. Since this class contains fullerene polytopes, we will describe fullerene graphs with maximal Wiener index. We will discuss combinatorics and volumes of right-angles polytopes, construction of 3-manifolds from right-angled blocks, and knots and links related to such manifolds.
Talk is based on joint works with A. Dobrynin [1] and A. Egorov [2,3].
