On problem of polarization tomography, I

The polarization tomography problem consists of recovering a matrix function f from the fundamental matrix of the equation $D\eta/dt=\pi_{\dot\gamma}f\eta$ known for every geodesic $\gamma$ of a given Riemannian metric. Here $\pi_{\dot\gamma}$ is the orthogonal projection onto the hyperplan $\dot\gamma^{\perp}$. The problem arises in optical tomography of slightly anisotropic media. The local uniqueness theorem is proved: a $C^1$- small function f can be recovered from the data uniquely up to a natural obstruction. A partial global result is obtained in the case of the Euclidean metric on $R^3$

Collection of compressible sediments by filtration

A complete mathematical model is proposed for the process of filtration separation of a suspension. The problem of collecting the sediment on a plane barrier in a regime of a specified pressure difference has been solved. © 1990 Plenum Publishing Corporation

Произведено сравнение инновационного кадрового потенциала Республики Татарстан с другими регионами.This article proposes an approach to the definition of innovative human resource capacity in the region. Assessment of human capacity in the field of innovation in the case of the Republic of Tatarstan in the period from 2012 to 2015 held. Comparison of the Republic of Tatarstan personnel potential with other regions

Migration factor in the context of national safety: Russian and foreign experience in the XXI century

© Serials Publications. The relevance of the problem is caused by the fact that in the XXI century globalization is one of the key processes in international politics, which directly promotes strengthening of migration flows. The aim of article is to study a relevant problem of national security, namely its migratory aspect operating under conditions of post-bipolar system of the international relations. The leading approach to the research of this problem is systematization of factors that allow using various scientific methods and techniques, mutually supplementing and combining themselves when investigating the international problems (including migratory processes). The main result of the research is the comprehensive study of the migratory factor in the context of national stability. On the one hand, it promotes the growth of human resources potential and stimulates economic growth in different branches of economy. On the other hand, there are difficulties in cross-cultural interaction; the risks of conflicts on ethnic and religious basis are increasing. The most dangerous phenomenon, from the point of view of the national security, is illegal migration, which strengthens possible risks. Now the Russian Federation and other developed countries, such as the USA, France and Germany connect solution of migratory problems with implementation of the policy of national security. The article can be useful for the scholars studying Russian and foreign experience both positive and negative aspects in the field of migration policy

Limiting Carleman weights and anisotropic inverse problems

In this article we consider the anisotropic Calderon problem and related inverse problems. The approach is based on limiting Carleman weights, introduced in Kenig-Sjoestrand-Uhlmann (Ann. of Math. 2007) in the Euclidean case. We characterize those Riemannian manifolds which admit limiting Carleman weights, and give a complex geometrical optics construction for a class of such manifolds. This is used to prove uniqueness results for anisotropic inverse problems, via the attenuated geodesic X-ray transform. Earlier results in dimension $n \geq 3$ were restricted to real-analytic metrics.Comment: 58 page
