New series of 3D lattice integrable models
In this paper we present a new series of 3-dimensional integrable lattice
models with colors. The case generalizes the elliptic model of our
previous paper. The weight functions of the models satisfy modified tetrahedron
equations with states and give a commuting family of two-layer
transfer-matrices. The dependence on the spectral parameters corresponds to the
static limit of the modified tetrahedron equations and weights are
parameterized in terms of elliptic functions. The models contain two free
parameters: elliptic modulus and additional parameter . Also we briefly
discuss symmetry properties of weight functions of the models.Comment: 17 pages, IHEP-93-126, Late
New solution of vertex type tetrahedron equations
In this paper we formulate a new N-state spin integrable model on a
three-dimensional lattice with spins interacting round each elementary cube of
the lattice. This model can be also reformulated as a vertex type model. Weight
functions of the model satisfy tetrahedron equations.Comment: 12 pages, LaTeX, IHEP-94-10
Regional politics of memory in Poland's Warmia and Masuria
A contribution to memory studies, this work focuses on Poland’s Warmian-Masurian voivodeship. Before the war, this territory and the neighbouring Kaliningrad region of Russia comprised the German province of East Prussia. In this article, we strive to identify the essence, mechanisms, key stages, and regional features of the politics of memory from 1945 to the present. To this end, we analyse the legal regulations, the authorities’ decisions, statistics, and the reports in the press. We consider such factors as the education sector, the museum industry, the monumental symbolism, the oral and printed propaganda, holidays and rituals, the institutions of national memory, the adoption of memory-related laws, and others. From the first post-war years, the regional authorities sought to make the Polonocentric concept of the region’s history dominate the collective consciousness. This approach helped to use the postwar legacy impartially and effectively. However, the image of the past was distorted. This distortion was overcome at the turn of the 21st century to give rise to the concept of open regionalism. An effective alternative to nationalistic populism, open regionalism provides a favourable background for international cross-border cooperation
- Vectors for Three Dimensional Models
In this paper we apply the method of psi-vectors to three dimensional
statistical models. This method gives the correspondence between the Bazhanov
-- Baxter model and its vertex formulation. Considering psi-vectors for the
Planar model, we obtain its self-duality.Comment: 11 pages, LaTeX, no figure
