An ansatz is proposed for heptagon relation, that is, algebraic imitation of five-dimensional Pachner move 4--3. Our relation is realized in terms of matrices acting in a direct sum of one-dimensional linear spaces corresponding to 4-faces.

The paper is devoted to the study of a special statistical model on graphs with vertices of degrees 6 and 1. We show that this model is invariant with respect to certain Roseman moves if one regards the graph as the singular point set of the diagram

Simultaneous measurement is considered for the working medium level and density by means of a system of two pressure sensors placed in the liquid at different levels and the use of a Kalman filter for filtering out the noise in this system. © 2007 S

A dynamical system in discrete time is studied by means of algebraic geometry. This system has reductions which can be interpreted as classical field theory in the 2+1 discrete space-time. The study is based on the technique of vacuum curves and vacu

The present paper continues partI (Zap. Nauchn. Semin. POMI,215,178–196 (1994)), in which a dynamical system in discrete time generazed by a birational transformation acting on the equivalence classes of matrices of specific form is introduced. We

A completely integrable dynamical system in discrete time is studied by methods of algebraic geometry. The system is associated with factorization of a linear operator acting in the direct sum of three linear spaces into a product of three operators,

The tetrahedron equation arises as a generalization of the famous Yang-Baxter equation to the2+1-dimensional quantum field theory and three-dimensional statistical mechanics. Not much is known about its solutions. In the present paper, a systematic m

Tetrahedral Zamolodchikov algebras are structures that occupy an intermediate place between the solutions of the Yang-Baxter equation and its generalization onto 3-dimensional mathematical physics — the tetrahedron equation. These algebras produce

We construct knot invariants on the basis of ascribing Euclidean geometric values to a triangulation of the sphere S 3, where the knot lies. Edges of the triangulation along which the knot goes are distinguished by a nonzero deficit angle, in the ter
