A semicanonical normal affine connection associated with the distribution
In manydimensional projective space distribution of planes is considered. The way of giving normal generalized affine connection associated with the distribution is proposed. It is shown that this connection is given by connection tensor and normal linear connection object. They define its curvature and torsion tensors. Semicanonical case is investigated when subtensor ...
Giving the 1st order affine connection by means of the 2nd order vector-valued forms
Affine connection is given by 2nd order vectors called horizontal. Vertical and horizontal forms of 2nd order are entered for 1st order affine connection. It is proved that symmetric affine connection in the bundle of tangent linear frames defines vertical linear ...
About generalizations of the Cartan projective connection on smooth manifold
The Laptev projective structure of the 1st order presented a fibering of special linear coframes with multidimensional gluing is considered. The Laptev linear connection by means of the object containing a tensor is set in this fibering. If the tensor vanishes we have preprojective connection from which canonical connection is marked out. The Cartan projective connection and its canonical version are obtained ...

Transport connectivity as a factor in overcoming challenges of the periphery: the case of rural areas in the Kaliningrad region
Quality of life in rural areas is increasingly dependent on transport links to nearest towns and regional centres. In this article, we examine transport connectivity between villages and towns in the Kaliningrad region. We use the travel time access parameter to investigate the influence of transport connectivity on the population size and the prospects of socio-economic development in rural areas with ...

Normal generalized affine connection associated with the Grassman-like manifold of centred planes
In projective space a Grassman-like manifold of centred planes is considered. The normal affine connection, associated with the manifold, is set in generalized fibering.

The border as a barrier and an incentive for the structural economic transformation of the Kaliningrad exclave
... isolation of the region from the main territory of the country necessitates transit through foreign countries during the overland transport of goods between the territory and mainland Russia. This circumstance objectively amplifies the role of external connections in the region’s developmental landscape.
The accession of neighbouring countries, Lithuania and Poland, to NATO and the EU in 2003—2004 further complicated interactions between the region and other Russian territories as they are now determined ...
Estonian ‘Balticness’ as a social construct: meanings and contextual specifics
... country’, which might be evoked in the mind of an external observer confronted with the term ‘Baltic States’. Estonian politicians also emphasise that in some respects (sometimes very specific ones, such as popular knowledge of English or internet connection quality), Estonia is not inferior to the Nordic countries. These achievements are opposed to the possible negative associations relating to ‘Soviet legacies’, for example, corruption [17, р. 192—193], [18, р. 356].

Translation Historiography

Driven by a move away from a Euro-centric view of translation, researchers have become interested in producing connected and comparative histories of translation. The dialogue with the general field of history has led to the adoption of new methods and forms of analysis, such as microhistory, histoire croisée, archival research, oral history and digital translation ...

Connections with partners from friendly countries are strengthening, particularly with other Russian regions. For example, a considerable portion of both freight and passenger transport to other Russian regions is now conducted through St. Petersburg ...
Population change and the settlement system transformation in Poland, as revealed by the 2021 census

Two of Poland’s key motorways go through it: the latitudinal one connecting Western Europe with Belarus and Russia and the longitudinal one connecting the Polish ports on the Baltic Sea with the Czech Republic and the more southern states of the European Union. Such a favourable economic and geographical location has ...
On connection between codependency and the ideas about abusive relationships in young women

Differential comparisons for the components of the curvature object of affine connection of the second order
Differential comparisons for the components of the curvature object of affine connection of the second order are received. These comparisons show that, in the general case, the second-order curvature object forms a geometric object only in conjunction with the first-order curvature object and the second-order connectivity object....

Covariant differentials and covariant derivatives associated with surface of projective space
The paper is concerned with m-dimensional surface in n-dimensional projective space. In studying fundamental-group connection Bianchi identities are found. It is proved that alternated covariant derivatives for the components of the first type connection object are equal to the corresponding components of the curvature tensor, and the ones of the third type vanish....
The concept of “network” in the system of basic concepts of regional economic geography

The author examines economic networks as organic systems characterised by resistance to external effects and comprised of interconnected economic agents from one or several related industries. A concentration of strong connections within such network constitutes its core or a cluster. Based on a retrospective analysis of studies into the spatial organisation of economy, it is concluded that there is a need to examine network forms from the perspective of regional socioeconomic ...
Geopolitical regionalisation of the Baltic area: the essence and historical dynamics

Considering Baltic land transport networks would not differ much from analysing the transport connectivity in, for example, the Central European region.
Several navigable canals connect the Baltic Sea with the River Elbe, which flows through territories near the Baltic Sea coast and carries the region’s river traffic. However, according to the ...

Grammar. Linguistics. Language (in response to opposing views)
I discuss the criteria of defining linguistics against other science branches. Linguistics is not a proper part of semiotics, since the foundations of language do not necessarily rely on the theory of sign systems. Grammar always operates on sets, including the sets consisting of one element. Not all language objects can be treated as signs. The connectors, i. e. segmental means marking the levels of clause linkage are legal linguistic objects, but the analysis of individual texts is a prerogative...
