A manifold of pure Gibbs states of the Ising model on the Lobachevsky plane

, 2013
In this paper we construct many ‘new ’ Gibbs states of the Ising model on the Lobachevsky plane, the millefeuilles. Unlike the usual states on the integer lattices, our foliated states have infinitely many interfaces.

The analytic continuation of volume and the Bellows conjecture in Lobachevsky spaces [PDF]

, 2015
A flexible polyhedron in an n-dimensional space of constant curvature, namely, in the Euclidean space, or in the Lobachevsky space, or in the sphere, is a polyhedron with rigid (n-1)-dimensional faces and hinges at (n-2)-dimensional faces.

Some Generalizations of the Shadow Problem in the Lobachevsky Space

, 2021
We consider the problem of shadow in the Lobachevsky space. This problem can be treated as the problem of finding conditions guaranteeing that points belong to the generalized convex hull of a family of sets.
