Today, almost all Russian-language mathematical journals are translated into English; however, there remains an interest in and demand for the original Russian scientific literature. This volume fulfills a need by scientists and translators for a dictionary with current terminology in probability theory, mathematical statistics, combinatorics, and their applications. Borovkov's dictionary, which is the only one that translates from Russian to English and English to Russian in these subject areas, will help specialists to read and understand Russian- language texts covering these topics. It is especially useful because it contains entries related to developments that have occurred in probability, statistics, and combinatorics over the past three decades. Each half of the dictionary contains approximately 7,500 terms and expressions, as well as the spelling of many names that appear in scientific and technical literature.
