Keywords: semifield, spectrum of semifield, left-primitivity, automorphism
Annotation: The author consider the algebraic properties of the semifield of order 64 that is one of two known counter-examples to G. Wene conjecture of left-primitivity for any finite semifield. The subfileds, automorphisms and spectrum are described. It is proved that the multiplicative loop of non-zero elements of this semifield is singly-generated

Linear inverse problem for the pseudo hyperbolic equations
Page:343-351
Release: 2016-2 (14)
Keywords: inverse problem of pseudo hyperbolic equation, Volterra equation, conditions override
Annotation: In this paper linear inverse problems for pseudo hyperbolic equations is considered. We prove the corresponding theorem on the unique solvability of the inverse problem
Application of the correlation adaptometry method in the inshurance markets analysis
Page:351-356
Release: 2016-2 (14)
Keywords: correlation adaptometry, effect of a group stress, dispersion, correlations, economic crisis, insurance market
Annotation: This paper presents the method of a correlation adaptometry for identification of pre-crisis and crisis situations in the insurance markets. Applicability of method is investigated based on statistical data of some regional insurance markets of the Russian Federation
Inverse problem for linear pseudoparabolic equation of filtration type
Page:357-363
Release: 2016-2 (14)
Keywords: local existence and uniqueness theorems, a priori estimates, inverse problems, pseudo-parabolic equations, filtration
Annotation: The paper discusses the inverse problem on determination of an unknown coefficient in the linear pseudoparabolic equations. The results obtained by the author and A. Tani earlier are extended to the case of the equation containing not only the unknown function, but its first derivatives as well. The assumptions on the input data are formulated wherein the local existence and uniqueness of the solution of the problem is proved
