Review of the Book “Peter I in Media Memory” by Denis S. Artamonov & Sophia V. Tikhonova
No full textThe subject of the review is a monographic study by S. V. Tikhonova and D. S. Artamonov “Peter I in Media Memory”. The monograph consists of three chapters and fourteen paragraphs. Co-authors analyze in the first chapter (“Peter I in the Media Memory of the Digital Age”) the influence of traditional (radio, cinema, television) and new (digital, interactive, social) media on the collective memory. The second chapter (“Peter the Great in the Visual images of Media Memory”) contains a study of historical anecdotes, cartoons, Internet memes, animated films, computer games. The third chapter (“Constructing the image of Peter I in the media environment”) is devoted to the politics of memory and memorial wars around Peter I in comparison with the figures of media memory closest to him – Ivan the Terrible and I. V. Stalin.
D. S. Artamonov and S. V. Tikhonova believe that in the 21st century, new media begins to play a major role in constructing the image of Peter the Great. The reviewed monograph is a truly innovative and searching study, which suggests methods and forms of analyzing the memory of Peter I in contemporary society that can be used in the study of other epochs, personalities, events of world and national history
Review of the Monograph “Peter the Great in Media Memory” by D. S. Artamonov and S. V. Tikhonova

С. Артамонова и С. В. Тихоновой «Петр I в медиапамяти». Соавторы монографии исходят из гипотезы, что в XXI в. ключевую роль в конструировании исторической памяти начинают играть медиасредства. Данную гипотезу они обосновывают, исследуя образ Петра I, создаваемый современной медиасредой. Первая глава монографии посвящена анализу трансформации исторической и коллективной памяти под влиянием различных медиасредств и цифровизации. Во второй главе исследуется специфика образа Петра I в медиапамяти. Третья глава посвящена изучению роли образа Петра I в политике памяти и мемориальных войнах. К несомненному достоинству монографии следует отнести удачно выбранный теоретический инструментарий, позволяющий на примере образа Петра I исследовать трансформационные процессы, свойственные современной коллективной памяти.The subject of the review is the monograph by D. S. Artamonov and S. V. Tikhonova “Peter I in the Media Memory”. The co-authors of the monograph proceed from the hypothesis that in the XXI century the key role in the construction of historical memory begins to play the media. D. S. Artamonov and S. V. Tikhonova substantiate this hypothesis by examining the image of Peter I, created by the modern media environment. The first chapter of the monograph analyzes the transformation of historical and collective memory under the influence of various media and digitalization. The second chapter explores the specificity of Peter I image in the media memory. The third chapter is devoted to the study of the role of the image of Peter I in the politics of memory and memorial warriors. Among the undoubted merits of the monograph is the well chosen theoretical toolkit, which allows us to study the transformation processes, typical for the modern collective memory, on the example of Peter I image
Faster Algorithms for Half-Integral T-Path Packing
No full textLet G = (V, E) be an undirected graph, a subset of vertices T be a set of terminals. Then a natural combinatorial problem consists in finding the maximum number of vertex-disjoint paths connecting distinct terminals. For this problem, a clever construction suggested by Gallai reduces it to computing a maximum non-bipartite matching and thus gives an O(mn^1/2 log(n^2/m)/log(n))-time algorithm (hereinafter n := |V|, m := |E|).
Now let us consider the fractional relaxation, i.e. allow T-path packings with arbitrary nonnegative real weights. It is known that there always exists a half-integral solution, that is, one only needs to assign weights 0, 1/2, 1 to maximize the total weight of T-paths. It is also known that an optimum half-integral packing can be found in strongly-polynomial time but the actual time bounds are far from being satisfactory.
In this paper we present a novel algorithm that solves the half-integral problem within O(mn^1/2 log(n^2/m)/log(n)) time, thus matching the complexities of integral and half-integral versions
Some Applications of Artamonov-Quillen-Suslin Theorems to Metabelian Inner Rank and Primitivity
No full textAbstractFor any variety of groups, the relative inner rank of a given groupG is defined to be the maximal rank of the -free homomorphic images of G. In this paper we explore metabelian inner ranks of certain one-relator groups. Using the well-known Quillen-Suslin Theorem, in conjunction with an elegant result of Artamonov, we prove that if r is any "Δ-modular" element of the free metabelian group Mn of rank n > 2 then the metabelian inner rank of the quotient group Mn/(r) is at most [n/2]. As a corollary we deduce that the metabelian inner rank of the (orientable) surface group of genus k is precisely k. This extends the corresponding result of Zieschang about the absolute inner ranks of these surface groups. In continuation of some further applications of the Quillen-Suslin Theorem we give necessary and sufficient conditions for a system g = (g1,..., gk) of k elements of a free metabelian group Mn, k ≤ n, to be a part of a basis of Mn. This extends results of Bachmuth and Timoshenko who considered the cases k = n and k < n — 3 respectively.</jats:p

Manifestation of the final states in completely momentum resolved coincidence spectroscopy RID G-7348-2011
No full textWe present the general method of analysis of the six-dimensional data measured in the momentum resolved e,2e reaction on the solid surfaces. The basis of the method is a normalization of the experimental density distribution on the model experimental function that describes the volume of available final states for this reaction in the momentum space. The density distributions of correlated electron pairs as functions of various variables are considered for the e,2e scattering on the Fe(110) surface. (C) 2002 Elsevier Science B.V.
