Włodzimierz Stożek
Włodzimierz Stożek (23 July 1883 – 3 or 4 July 1941) was a Polish mathematician of the Lwów School of Mathematics. Head of the Mathematics Faculty on the Lwów University of Technology. He was arrested and murdered together with his two sons: the 29-year-old engineer Eustachy and 24-year-old Emanuel, graduate of the Institute of Technology by Nazis during the Second World War on 3 or 4 July in Lviv, during the Massacre of Lviv professors. In December 1944, Stefan Banach wrote the following tribute to Stożek: :Professor Włodzimierz Stożek was an outstanding mathematician, the author of numerous papers on the theory of integral equations, potential theory In mathematics and mathematical physics, potential theory is the study of harmonic functions.

Zhovkva
Zhovkva ( uk, Жовква ; pl, Żółkiew; yi, זאָלקוואַ, translit=Zolkva; russian: Жо́лква, 1951–1992: ''Nesterov'') is a city in Lviv Raion, Lviv Oblast (region) of western Ukraine.

History A village named ''Winniki'' was mentioned at the site in 1368 and was part of the Kingdom of Poland under the Piast dynasty. The town was founded in 1597 as a private fortified town and named ''Żółkiew'' after its founder, one of the most accomplished military commanders in Polish history, hetman Stanisław Żółkiewski. Like Zamość, which was founded by Żółkiewski's mentor Jan Zamoyski, Żółkiew was built on an ideal Renaissance city plan. Due to its strategic location at the intersection of important trade routes, the town prospered.Ruth Ellen Gruber.For a fortress town, a second renaissance. January 12, 2009. The New York Times ...

Massacre Of Lviv Professors
A massacre is the killing of a large number of people or animals, especially those who are not involved in any fighting or have no way of defending themselves. A massacre is generally considered to be morally unacceptable, especially when perpetrated by a group of political actors against defenseless victims. The word is a loan of a French term for "butchery" or "carnage". A "massacre" is not necessarily a "crime against humanity". Other terms with overlapping scope include war crime, pogrom, mass killing, mass murder, and extrajudicial killing. Etymology The modern definition of ''massacre'' as "indiscriminate slaughter, carnage", and the subsequent verb of this form, derive from late 16th century Middle French, evolved from Middle French ''"macacre, macecle"'' meaning "slaughterhouse, butchery". Further origins are dubious, though may be related to Latin ''macellum'' "provisions store, butcher shop". The Middle French word ''macecr'' "butchery, carnage" is first recor ...

Lviv Polytechnic Alumni
Lviv ( uk, Львів) is the largest city in western Ukraine, and the seventh-largest in Ukraine, with a population of . It serves as the administrative centre of Lviv Oblast and Lviv Raion, and is one of the main cultural centres of Ukraine. It was named in honour of Leo, the eldest son of Daniel, King of Ruthenia. Lviv emerged as the centre of the historical regions of Red Ruthenia and Galicia in the 14th century, superseding Halych, Chełm, Belz and Przemyśl. It was the capital of the Kingdom of Galicia–Volhynia from 1272 to 1349, when it was conquered by King Casimir III the Great of Poland. From 1434, it was the regional capital of the Ruthenian Voivodeship in the Kingdom of Poland. In 1772, after the First Partition of Poland, the city became the capital of the Habsburg Kingdom of Galicia and Lodomeria. In 1918, for a short time, it was the capital of the West Ukrainian People's Republic. Between the wars, the city was the centre of the Lwów Voivodeship in the Se ...

Potential Theory
In mathematics and mathematical physics, potential theory is the study of harmonic functions. The term "potential theory" was coined in 19th-century physics when it was realized that two fundamental forces of nature known at the time, namely gravity and the electrostatic force, could be modeled using functions called the gravitational potential and electrostatic potential, both of which satisfy Poisson's equation—or in the vacuum, Laplace's equation. There is considerable overlap between potential theory and the theory of Poisson's equation to the extent that it is impossible to draw a distinction between these two fields. The difference is more one of emphasis than subject matter and rests on the following distinction: potential theory focuses on the properties of the functions as opposed to the properties of the equation. For example, a result about the singularities of harmonic functions would be said to belong to potential theory whilst a result on how the solution depe ...

Integral Equation
In mathematics, integral equations are equations in which an unknown function appears under an integral sign. In mathematical notation, integral equations may thus be expressed as being of the form: f(x_1,x_2,x_3,...,x_n ; u(x_1,x_2,x_3,...,x_n) ; I^1 (u), I^2(u), I^3(u), ..., I^m(u)) = 0where I^i(u) is an integral operator acting on ''u.'' Hence, integral equations may be viewed as the analog to differential equations where instead of the equation involving derivatives, the equation contains integrals. A direct comparison can be seen with the mathematical form of the general integral equation above with the general form of a differential equation which may be expressed as follows:f(x_1,x_2,x_3,...,x_n ; u(x_1,x_2,x_3,...,x_n) ; D^1 (u), D^2(u), D^3(u), ..., D^m(u)) = 0where D^i(u) may be viewed as a differential operator of order ''i''. Due to this close connection between differential and integral equations, one can often convert between the two. For example, one method of solvi ...

Stefan Banach
Stefan Banach ( ; 30 March 1892 – 31 August 1945) was a Polish mathematician who is generally considered one of the 20th century's most important and influential mathematicians. He was the founder of modern functional analysis, and an original member of the Lwów School of Mathematics. His major work was the 1932 book, ''Théorie des opérations linéaires'' (Theory of Linear Operations), the first monograph on the general theory of functional analysis. Born in Kraków to a family of Goral descent, Banach showed a keen interest in mathematics and engaged in solving mathematical problems during school recess. After completing his secondary education, he befriended Hugo Steinhaus, with whom he established the Polish Mathematical Society in 1919 and later published the scientific journal ''Studia Mathematica''. In 1920, he received an assistantship at the Lwów Polytechnic, subsequently becoming a professor in 1922 and a member of the Polish Academy of Learning in 1924. Ba ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
