Volodymyr Levytsky
Volodymyr Levytsky (31 December 1872 – 13 August 1956) was a Ukrainian mathematician who taught mathematics and studied functions of a complex variable. Biography and education Volodymyr Levytsky finished his doctorate at the University of Lviv The Ivan Franko National University of Lviv (named after Ivan Franko, ) is a state-sponsored university in Lviv, Ukraine. Since 1940 the university is named after Ukrainian poet Ivan Franko. The university is the oldest institution of highe ... in 1901 and went on to teach mathematics and physics at high schools. After the First World War Ukrainian students were not allowed to enrol at the university and in 1920 Ukrainian professors were also banned, leaving only Polish lecturers. As a result, the Ukrainian students set up an underground university at the university in July 1921. From the beginning Levytsky taught mathematics at this new underground university for a few years until it was forced to close in 1925. Levytsky was t ...

Its Polish name, ''Tarnopol'', means 'Tarnowski's city' and stems from a combination of the founder's family name and the Greek term ''polis''.

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

Functions Of A Complex Variable
Complex analysis, traditionally known as the theory of functions of a complex variable, is the branch of mathematical analysis that investigates functions of complex numbers. It is helpful in many branches of mathematics, including algebraic geometry, number theory, analytic combinatorics, and applied mathematics, as well as in physics, including the branches of hydrodynamics, thermodynamics, quantum mechanics, and twistor theory. By extension, use of complex analysis also has applications in engineering fields such as nuclear, aerospace, mechanical and electrical engineering. As a differentiable function of a complex variable is equal to the sum function given by its Taylor series (that is, it is analytic), complex analysis is particularly concerned with analytic functions of a complex variable, that is, ''holomorphic functions''. The concept can be extended to functions of several complex variables. Complex analysis is contrasted with real analysis, which deals with th ...

University Of Lviv
The Ivan Franko National University of Lviv (named after Ivan Franko, ) is a state-sponsored university in Lviv, Ukraine. Since 1940 the university is named after Ukrainian poet Ivan Franko. The university is the oldest institution of higher learning in continuous operation in present-day Ukraine, dating from 1661 when John II Casimir, King of Poland and Grand Duke of Lithuania, granted it its first royal charter. Over the centuries, it has undergone various transformations, suspensions, and name changes that have reflected the geopolitical complexities of this part of Europe. The present institution can be dated to 1940. History Polish–Lithuanian Commonwealth The university was founded on 20 January 1661, when King and Grand Duke John II Casimir granted a charter to the city's Jesuit Collegium, founded in 1608, giving it "the honor of an academy and the title of a university". In 1589, the Jesuits had tried to found a university earlier, but did not succeed. Establ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shevchenko Scientific Society
The Shevchenko Scientific Society (), founded in 1873, is a Ukrainian scientific society devoted to the promotion of scholarly research and publication. Unlike the government-funded National Academy of Sciences of Ukraine, the society is a public organization. It was reestablished in Ukraine in 1989 during the fall of the Soviet Union, after being exiled from Ukraine since 1940. The society now has branches in several countries around the globe, such as the United States, Canada, Australia, and France. The organisation is named after the famous Ukrainian poet, writer, artist, public and political figure, Taras Shevchenko. History It was founded in 1873 in Lemberg (today Lviv), at that time the capital of the Austrian crown land of Kingdom of Galicia and Lodomeria, as a literary society devoted to the promotion of Ukrainian language literature initially under the name Shevchenko Society. It was established soon after another cultural society, better known as Prosvita (Enlight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
