Andrei Vesnin "Around right-angled hyperbolic polytopes"
Andrei Vesnin from Tomsk State University will give the talk "Around right-angled hyperbolic polytopes" on the labs' Big Seminar.
Password: first 6 decimal places of $\pi$ after the decimal point
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  and A. Egorov [2,3].
