Abstract
A new class of integral operators with fiber singular type homogeneous kernels in the space Lp(R2) is introduced. This new class includes the class of operators with SO(2)-invariant homogeneous kernels. For Banach algebra of pair operators with fiber singular type homogeneous kernels the symbol calculus is constructed and the criterion of Fredholmness is obtained.

Authors give the solution of linear discrete difference equation of infinite order, in the sequences space., They propose description of correspondence difference operators in the classes of infinite matrix operators.

MATERIALS SCIENCE

Abstract
Melt crystallization peculiarities of the system have been investigated by means of X-Ray diffraction and microstructure analysis. It is shown that content changing of hexagonal tungsten carbide in the mixture essentially influences processes of phases formation at crystallization. It is ascertained that tungsten carbide having hexagonal structure partly transforms to the double carbide FeW3C, which under the terms of carbon shortage transits to superlattices of the type M6C.

Abstract
In work the processes of structure formation of a pipe steel under action of various kinds and modes of heat treatment (at furnace or induction heating) are investigated. The efficiency of induction hardening of oil-and-gas pipes from an intercritical interval of temperatures is shown. This mode in a combination with other kinds of heat treatment (normalization, full hardening and tempering) is provided jump of a yield point and especially a cold resisting property of steel (almost on the order at the temperature of test −70°С). At that the steel resistance to some kinds of corrosion trouble, which are featured for the soil of Siberia and Far North, is increased appreciablly.

Abstract
The Central bank conducts a monetary policy. The targets of monetary policy are an unemployment, inflation, economic growth, stability financial markets. The main problem of monetary policy it is impossible to control all this targets. The Bank of Russia realizes a monetary target to. The main target of Bank of Russia since 1992 year is level of inflation.

Abstract
The article provides the analysis of algorithmization as one of the forms of formalization used as a logical and epistemological means to construct abstract mathematical objects in terms of classical rationality. Mathematical theorized knowledge is considered in the article as an object of consolidation and minimization principles application for dialectical and methodological analysis of its form and content. Algorithmization is presented as a form of mathematical knowledge minimization in the process of its consolidation.

Abstract
Daily speech of the person proves, that «the structure of language is not settled only by intellectual or sound factors» [1]. Corresponding language installation lays in a basis of the mechanism of speech, reading and lettering in each concrete language. Using of theoretically-methodological positions of the theory of installation by teachers of science during of 30-years practice of annual training of foreign students is shown in this particular article.
