Оптимизация рекламных стратегий на российском телевидении: возможности и проблемы
In this research we use the part of RLMS data about the innovation in the lifestyles of Russian collected in 2009. Some typologies of Russian people were constructed based on their inclination to innovation, computer skills and media consumption. The last one is measured there as the differentiation of practices of internet and mobile telephone function use. The quantitative digital inequality in the accessibility of computer and internet was found. But there is the other type of digital inequality the quantitative one. It is due to the differentiation of the type of media consumption. This inequality also depends on the such factors as age, income and education level.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
