In the present paper, we discuss the notion of 'tropical mathematics' in view of the fact that, up to the present time, there is no generally accepted correct understanding of this notion. The paper presents, rather than mathematical proofs, humanitarian and social justification of the correct understanding of the term. The author proposes to describe the ...

В свете текущих дебатов о кризисе воспроизводимости в социальных науках, данная статья обращается к основаниям современной частотной статистики в аспекте установления причинных выводов. Чтобы понять как и для чего статистический анализ данных был введён в научную практику, после краткого введения в сегодняшний этап дискуссии о кризисе воспроизводимости, было описано понимание назначения частотного статистического анализа данных ...

The article discusses approaches to objective nontransitiveness of superiority (A is superior, more competitive than B, B - C, C - A) in several scientific areas (mathematics, biology, economics, decision-taking theory) which have turned nontransitiveness of superiority into an object of special research. The author analyzes relations between the ‘mainstream’ in a specific area and ...

Matrix factorization problems over various semirings naturally arise in different contexts of modern pure and applied mathematics. These problems are very hard in general and cause computational difficulties in applications. We give a survey of what is known on the algorithmic complexity of Boolean, tropical, nonnegative, and positive semidefinite factorizations, and we examine the behavior ...

The max-times algebra is the set R+ of nonnegative reals with operations ⊕:(a,b)→max{a,b} and ⊙:(a,b)→ab. We discuss the property of matrices to be squares of max-times or conventional nonnegative matrices. We prove that there exists a matrix having a conventional nonnegative square root but no max-times square root. Also, we present a set S of cardinality three for which there is a ...

Рассматриваются и сравниваются подходы современной экономической науки и психологии к анализу индивидуального поведения, прежде всего в контексте современных теорий выбора в условиях риска. При кажущемся формальном различии между этими науками у них обнаруживается немало общих черт, охватывающих как экспериментальные методы, так и рационалистические теоретические подходы к осмыслению и описанию человеческого поведения. Это проявляется, в частности, ...

We analyzed a generic relaxation oscillator under moderately strong forcing at a frequency much greater that the natural intrinsic frequency of the oscillator. Additionally, the forcing is of the same sign and, thus, has a nonzero average, matching neuroscience applications. We found that, first, the transition to high-frequency synchronous oscillations occurs mostly through periodic solutions ...

Response delay is an inherent and essential part of human actions. In the context of human balance control, the response delay is traditionally modeled using the formalism of delay-differential equations, which adopts the approximation of fixed delay. However, experimental studies revealing substantial variability, adaptive anticipation, and non-stationary dynamics of response delay provide evidence against this approximation. In this ...

This article hypothesizes that in societies where spouses are considered to have relatively equal status, they are more likely to be intimate with one another than in societies where there is spousal status inequality. The authors ask: What are the core attributes of intimacy between husband and wife cross-culturally? And what sociocultural norms and practices are ...

Показана возможность нетранзитивных шахматных позиций, анализируются связанные с этим возможные шахматно-математические задачи. В заключение обсуждается проблема понимания людьми объективных нетранзитивных отношений превосходства (предпочтительности и пр.) в различных системах. ...
