On the history of graph theory. Origin
The family tree as an ancient unscientific use of graphs is not always a tree in the mathematical sense and may include cycles. Another ancient unscientific use of graphs is the image of the starry sky:
— just a drawing of stars — a graph without edges;
— asterisms and arrangements of stars ...
Ideas of Kant’s theoretical philosophy in Peirce’s graph theory
... their content, and transformed analytic and synthetic judgements into ampliative and explicative reasoning. Kant helped Peirce to overcome the doctrine of nominalism and develop the doctrine of critical realism. This paper addresses the existential graph theory, which is scrutinised from the perspective of transformations of Kant’s ideas. The graph theory was chosen, firstly, because of its chronological significance — it is the last logical theory of the American thinker. Secondly, it was greatly ...
Analysis of the application of mathematical modeling in geology
In this paper, the most characteristic errors in the application of mathematical-statistical and model methods that periodically occur during the review of scientific geological journals were analyzed, and recommendations for their elimination were given. The problems of determining relative errors in simplified mathematical models are discussed. The necessity of calculating the parameters of the background value and excluding its influence on the calculation of the “useful signal” is shown....
Typographic landscape in urban space: a sociolinguistic approach
This paper suggests a sociolinguistic approach to typographic landscape analysis. Typography is discussed as a semiotic resource with meaning-making potential. The paper argues that typographic variation provides dynamic indexical links to social practice. It obtains its ‘social voice’ and becomes an integral part of the social context in which it is perceived as typical and able to generate particular socially loaded meanings. This research is in line with contemporary social semiotics, interactional...
The philosophical aspects of graphical diagnostics
This paper offers a philosophical analysis of graphic tests, which have become predominant recently. Drawing tests, as a model of hierarchical interrelations and inversions in the psychic structure, are an important object of philosophical research. By means of this model, we can learn a lot about hierarchical systems. The author relied on the presence of a hierarchical system in human activity stated by the great Russian physiologist Nikolai Bernstein.

Development of network business structures in the spatially distributed cluster St. Petersburg-Leningrad region-Kaliningrad region as a tool of interregional interaction
In the current conditions of increasing geopolitical tension and volatility in the global economy, the development of interregional interaction is increasingly seen as a source of economic growth for Russian regions. However, the study of such interaction should not only include an analysis of trade flows but also an analysis of network interaction, an attempt to carry out which is presented in this work. The article presents the results of a study analyzing the presence of Saint Petersburg companies...

Application of spatial analysis of morbidity and mortality from COVID-19 (the case of the Pskov region)
Apart from biomedical and organizational issues, the emergence of the new coronavirus COVID-19 (SARS-CoV-2) pandemic, set large-scale tasks for creating and improving mathematical and information technologies that operate spatial data in statistical analysis and forecasting. The regional level is seen as a suitable choice for spatial analysis of COVID-19 morbidity and mortality due to the availability of statistics, as well as data on geographical patterns, characteristics of the distribution space...
Evolution of civil promotion in rank in the Russian empire in the 18th and 19th centuries
The author studies governmental measures to regulate the sphere of promotion in rank in the Russian Empire analyzing new data obtained from unpublished documents of the Russian State Historical Archive (RGIA). Documents demonstrate the role of the Table of Ranks of Peter I and its influence on the development of civil ranks in the Russian Empire. The issues of uncontrolled growth of the bureaucracy and abuse of civil ranks for the rapid career advancement of civil servants are seen to be essential...
Composition and functions of the software of the geographical information system (on the example of Maptitude)
In the modern world, the process of developing and implementing innovative information updating systems is rapidly developing, and geographic information systems are no exception, which, having a complex structure, require regular updating of information in various formats. The purpose of the article is to analyze the systems used in the creation of GIS mapping software. Geographic Information System (GIS software) is designed to store, retrieve, manage, display and analyze all types of geographic...

Finding optimal BKZ parametrs for NTRU lattice reduction
... attack parameters. The algorithm developed during the work on this article is quite fast and requires O(log2n) log of time to return results where n is the dimension of lattice. Its correctness has been verified by numerical experiments. As a result, graphs are shown connecting the parameters of the lattice and the minimum smallest parameters necessary for its successful reduction.

Modern geopolitical research in Russia
In this article, we present the results of our study into the contribution of geography to modern geopolitics in Russia. We stress the interdisciplinary nature of geopolitical studies and identify ensuing problems. Using content analysis of the eLIBRARY bibliography database and Elsevier’s abstract and citation database Scopus, we conclude that geography has considerably affected the development of modern geopolitics in Russia. The contribution of geographers is rather modest considering the...
Modeling of the image of the problem situation of medical diagnostics: challenges and state of the question
The paper considers the topicality and challenges of the approach for improving the quality of diagnosis by modelling of the image of diagnostics medical problem as an imitation of integrated combined visual-figurative and verbal-sign representations of the diagnostic problem by experts, and also by modelling collective restructuring of the reduced representation of the problem according to the conception of the council using hybrid intelligent systems as diagnostic decision support systems...
Visualization of the esthetics of memories in the novels of W. G. Sebald «The Rings of Saturn» and «Austerlitz»
The article explores the meaning and functions of photography in W. G. Sebald's works exemplified by his novels “The Rings of Saturn” and “Austerlitz”. The relevance of the study of the intermediary component, the photographic one, in the novels of the German writer is confirmed by the abundance of works on this problem written by Western literary critics. Early novels of W. G. Sebald have been studied in more detail. Photography performs an illustrative function in them. In “The...
