The article opens a cycle of three consecutive publications dedicated to the phenomenon of the displacement of the same points in overlapping scans obtained adjacent CCD matrices with opto-electronic imagery. This phenomenon was noticed by other authors, but the proposed explanation for the origin of displacements and the resulting estimates are insufficient, and developed their solutions seem controversial from the point of view of recovery of the measuring accuracy of opticalelectronic space images, determined by the physical laws of their formation. In the first article the mathematical modeling of the expected displacements based on the design features of a scanning opto-electronic imaging equipment. It is shown that actual bias cannot be forecast, because they include additional terms, which may be gross, systematic and random values. The proposed algorithm for computing the most probable values of the additional displacement and ways to address some of the systematic components of these displacements in a mathematical model of optical-electronic remote sensing.

The article follows the narrative trend initiated by the social media posts and fake news during the first months of the corona quarantine, which claims that the decrease of contamination due to the quarantine has a positive effect on the environment and nature recovery. The author describes the context of the topic and follows the changes in the rhetoric through different genres, discussing the ways in which a picture can tell a truthful story. What is the relation between the context, truth, and rhetoric? This material spread globally, yet it was also readily “translated” into the Estonian context, and – what is very characteristic of the entire pandemic material – when approaching this material, truthful and fabricated texts, photos, and videos were combined. From the folkloristic point of view, these rumours in the form of fake news, first presented in the function of a tall tale and further following the sliding truth scale of legends, constitute a part of coping strategies, so-called crisis humour, yet, on the other hand, also a belief story presenting positive imagery, which surrounds the mainly apocalyptically perceived pandemic period and interprets the human existence on a wider scale. Even if these fake news and memes have no truth value, they communicate an idea – nature recovers – and definitely offer hope and a feeling of well-being.

Detailed Assessment

The conditions for doing business at this stage are often similar in a game in which you need to calculate your actions a few steps ahead. At the same time, it is important to highlight several possible current options and make the necessary decision at the control moment. Moreover, each of the options formed should be justified, understandable and take into account the risk factors and available resources.Today, the main problem of assessing and minimizing the risk of “unfriendly takeover” is due to the fact that in most cases the raider is a player who acts quite legitimately and relies on the loopholes of the current legislative framework. Therefore, it is easier to identify possible actions of the raider and to avoid them within the limits of the reverse game than to deal with the consequences.The purpose of the research is to study the specificity of the individualized assessment and minimization of the risk of “unfriendly takeover” by using elements of game theory.It has been taken into account that the effect of individualization in assessing the risk of unfriendly takeover of enterprises can possibly be achieved on the basis of the application of game theory, the elements of which provide simulation of the unfriendly takeover process within the mathematical description of the inherent combinations of attack/defence as if they actually occurred in time both within one state of the external environment and for their given set.The results allowed forming mathematical decision-making models based on the elements of the antagonistic game “raider-target enterprise” and “raider games with the external environment”, which proved the possibility to: 1) identify possible functions of wins/losses; 2) combinations of attacks that can be neglected (that is, from the point of view of the rationality of decisions, will be rejected by the raider); 3) the ranking of the raider’s “attack combinations” for the reliability of their use during “unfriendly takeover”. Under such conditions, the target company can provide not only a detailed assessment, but also an effective minimization of the risk of “unfriendly takeover” and allocate the best combination of protection.

The Relationship

Recently, the methods of gametheoretic modeling are increasingly used in the financial sphere. In particular, the formation of an optimal investment portfolio is considered and analyzed from the point of view of game theory as a type of cooperative game. In business, game theory is widely used to model the behavior between competitors. Economists often use game theory to understand the behavior of oligopolies, trying to calculate when firms collude. The relevance of game theory methods for the financial and economic sphere is due to their universality, as well as mathematical validity. This article examines how using the concepts contained in game theory, it is possible not only to build real scenarios for such situations as price competition, production and output, the relationship between buyer and seller, but also to predict their results. The purpose of this article is to study the basic concepts of game theory, as well as to consider practical approaches to solving specific situations that are reflected in the financial and economic sphere

The sector of micro, small and medium size enterprises is important for any economy. It is important also for Poland. Analyzing the industrial organization of this sector it was confirmed that the owners and managers of such companies are applying strategies, which are rational from their point of view, but not from the perspective of real market conditions. It is argued therefore that the game theory is for them a solution in enhancing competences and performance of their organizations. Based on randomized sample of Polish micro and small companies the paper aimed to find out if the managers apply the game theory rationales when choosing price strategy when enter the market. It was confirmed that they do not and that they don't play Nash equilibrium in the strategic interaction when it comes to the price level. There was applied maxmin strategy, which maximises the worst - case scenario from the game. Thus there is a real chance that if entrepreneurs would analyze the situation with respect of game theory, their strategies would be more accurate and provide better outcomes.

Abstract The aim of this article is to analyze the independence activities undertaken by the Catalan government in the context of the brinkmanship strategy and the assumptions of game theory based on “the game of chicken”. It allows us to put the issue of Catalan’s claims in a different context than to refer to political, historical or cultural grounds for self-determination. By adopting this approach to the problem and putting it in the field of political competition at central and national level, it is possible to expose the elements that treat the whole problem as a political game, rather than a real endeavor to reach a consensus between the parties and finally solve the problem. In addition, from the point of view of party interests, it is beneficial that the problem of Catalan independence, absorbing much public attention, continues to function in the political sphere and in the consciousness of the people.

International audience This paper contains two short presentations related to the mathematical modeling of Cancer. The first part intends to introduce a tumour-immune system interaction, which describes the early dynamics of cancerous cells, competing with the immune system, potentially leading to either the elimination of tumoral cells or to the viability of a solid tumor. The second part of the paper addresses the case where a solid tumor has grown enough to initiate angiogenesis, a process which equips the tumor with its own blood network. Nash game theory is used to model the interaction between activators and inhibitors of the angiogenesis process.
