Romanas Januškevičius
Romanas Januškevičius (sometimes transliterated from Russian as Romanas Yanushkevichius; born July 10, 1953) is a Lithuanian mathematician who worked in probability theory and characterization of probability distributions and its stability. He was a professor at the Lithuanian University of Educational Sciences, head of the Department of Mathematics, Informatics and Physics since 2001 until 2017. Early life Januškevičius was born in Vilnius on July 10, 1953. He graduated from one of Vilnius high schools in 1971 and entered Vilnius University, from which he graduated in 1976. In 1976–1978 Januškevičius trained in Steklov Institute of Mathematics in Moscow, where under the guidance of ProfessoVladimir Zolotarevwrote and in 1978 defended his thesis "Investigation of stability in some problems of characterization of distributions" and received the Candidate of Sciences degree. The main result of this thesis was the work of the author, which considered the stability for dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vilnius
Vilnius ( , ) is the capital of and List of cities in Lithuania#Cities, largest city in Lithuania and the List of cities in the Baltic states by population, most-populous city in the Baltic states. The city's estimated January 2025 population was 607,667, and the Vilnius urban area (which extends beyond the city limits) has an estimated population of 747,864. Vilnius is notable for the architecture of its Vilnius Old Town, Old Town, considered one of Europe's largest and best-preserved old towns. The city was declared a World Heritage Site, UNESCO World Heritage Site in 1994. The architectural style known as Vilnian Baroque is named after the city, which is farthest to the east among Baroque architecture, Baroque cities and the largest such city north of the Alps. The city was noted for its #Demographics, multicultural population during the Polish–Lithuanian Commonwealth, with contemporary sources comparing it to Babylon.

Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in Germany, France, Italy, Poland and some other European and non-English-speaking countries. The candidate fulfills a university's set criteria of excellence in research, teaching, and further education, which usually includes a dissertation. The degree, sometimes abbreviated ''Dr. habil''. (), ''dr hab.'' (), or ''D.Sc.'' ('' Doctor of Sciences'' in Russia and some CIS countries), is often a qualification for full professorship in those countries. In German-speaking countries it allows the degree holder to bear the title ''PD'' (for ). In a number of countries there exists an academic post of docent, appointment to which often requires such a qualification. The degree conferral is usually accompanied by a public oral defence event (a lecture or a colloquium) with one or more opponents. Habilitation is usually awarded 5–15 years after a PhD degree or its equivalent. Achieving this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Probability Theorists
Probability is a branch of mathematics and statistics concerning events and numerical descriptions of how likely they are to occur. The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th ed., (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', vol. 1, 3rd ed., (1968), Wiley, . This number is often expressed as a percentage (%), ranging from 0% to 100%. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%). These concepts have been given an axiomatic mathematical formaliza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Vilnius
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Number Theorists
Number theory is a branch of pure mathematics devoted primarily to the study of the integers and arithmetic functions. Number theorists study prime numbers as well as the properties of mathematical objects constructed from integers (for example, rational numbers), or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations ( Diophantine geometry). Questions in number theory can often be understood through the study of analytical objects, such as the Riemann zeta function, that encode properties of the integers, primes or other number-theoretic objects in some fashion (analytic number theory). One may also study real numbers in relation to rational numbers, as for instance how irrational numbers can be approximated by fractions (Diophantine approximation). Number theory is one of the oldest branches of mathematics alongside geometry. One quirk of number theory is that it deals wi ...

Patriarch Alexy II Of Moscow
Patriarch Alexy II (or Alexius II, ; secular name Aleksei Mikhailovich Ridiger ; 23 February 1929 – 5 December 2008) was the 15th Patriarch of Moscow and all Rus', the primate of the Russian Orthodox Church. Elected Patriarch of Moscow in 1990, eighteen months before the dissolution of the Soviet Union, he became the first Russian Patriarch of the post-Soviet period. Family history Alexey Mikhailovich Ridiger was a patrilineal descendant of a Baltic German noble family. His father, Mikhail Aleksandrovich Ridiger (1900–1960), was a descendant of Captain Heinrich Nikolaus (Nils) Rüdinger, commander of a Swedish fortification in Daugavgrīva, Swedish Livonia and knighted by Charles XI of Sweden in 1695. Swedish Estonia and Swedish Livonia became part of the Russian Empire in the aftermath of the Great Northern War, in the beginning of the 18th century. Friedrich Wilhelm von Rüdiger (1780–1840), adopted Orthodox Christianity during the reign of Catherine the Great. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
