No full textOn Tychonoff-type Hypertopologies.
No full textIn 1975, M. M. Choban \cite{C} introduced a new topology on the set
of all closed subsets of a topological space, similar to the Tychonoff topology but weaker than it. In 1998, G. Dimov and D. Vakarelov \cite{DV} used a generalized version of this new topology, calling it Tychonoff-type topology. The present paper is devoted to a detailed study of Tychonoff-type topologies on an arbitrary family \MM of subsets of a set . When \MM contains all singletons, a description of all Tychonoff-type topologies \OO on \MM is given. The continuous maps of a special form between spaces of the type (\MM,\OO) are described in an isomorphism theorem. The problem of {\em commutability between hyperspaces and subspaces with respect to a Tychonoff-type topology} is investigated as well. Some topological properties of the hyperspaces (\MM,\OO) with Tychonoff-type topologies \OO are briefly discussed

О бикомпактных расширениях периферически бикомпактных пространств с наростами специального вида
No full text[Dimov Georgi D.; Димов Георги Д.]В статье на основании результатов Скляренко [6], предлагается новый метод, с помощью которого удается охарактеризовать различные свойства наростов периферически бикомпактных пространств в терминах самих пространств. Точнее, рассматриваются следующие свойства наростов: π-вес, мощность, дискретность (локальная бикомпактность) при заданной мощности, отсутствие точек локальной бикомпактности
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
