On the Volterra property of a boundary problem with integral gluing condition for mixed parabolic-hyperbolic equation

In the present work we consider a boundary value problem with gluing conditions of integral form for parabolic-hyperbolic type equation. We prove that the considered problem has the Volterra property. The main tools used in the work are related to the method of the integral equations and functional analysis.Comment: 18 page

Quasi-Two Dimensional Diluted Magnetic Semiconductors with Arbitrary Carrier Degeneracy

In the framework of the generalized mean field theory, conditions for arising the ferromagnetic state in a two-dimensional diluted magnetic semiconductor and the features of that state are defined. RKKY-interaction of magnetic impurities is supposed. The spatial disorder of their arrangement and temperature alteration of the carrier degeneracy are taken into account

THE FUTURE OF THE CRYPTOCURRENCY MARKET

The history of creating bitcoin cryptocurrencies has been considered, the main features of cryptocurrencies and cryptocurrency market have been identified. Based on the identification of features of the blockchain technology, the possibilities of making settlements outside the traditional financial system have been determined. Special attention has been paid to the issue of legal regulation of cryptocurrency in various countries. According to the results of a study of current trends in the cryptocurrency market, in the conditions of a significant decline in the market value of bitcoin in 2018, as the flagship of the cryptocurrency market, prospects for its development have been determine
