Zygmund Dobbs
Antoni Zygmund (December 25, 1900 – May 30, 1992) was a Polish mathematician. He worked mostly in the area of mathematical analysis, including especially harmonic analysis, and he is considered one of the greatest analysts of the 20th century. Zygmund was responsible for creating the Chicago school of mathematical analysis together with his doctoral student Alberto Calderón, for which he was awarded the National Medal of Science in 1986. Biography Born in Warsaw, Zygmund obtained his Ph.D. from the University of Warsaw (1923) and was a professor at Stefan Batory University at Wilno from 1930 to 1939, when World War II broke out and Poland was occupied. In 1940 he managed to emigrate to the United States, where he became a professor at Mount Holyoke College in South Hadley, Massachusetts. In 1945–1947 he was a professor at the University of Pennsylvania, and from 1947, until his retirement, at the University of Chicago. He was a member of several scientific societies. Fro ...

Occupation Of Poland (1939–1945)
The occupation of Poland by Nazi Germany and the Soviet Union during World War II (1939–1945) began with the German-Soviet invasion of Poland in September 1939, and it was formally concluded with the End of World War II in Europe, defeat of Germany by the Allies in May 1945. Throughout the entire course of the occupation, the territory of Poland was divided between Nazi Germany and the Soviet Union (USSR) both of which intended to eradicate Poland's culture and subjugate its people. In the summer-autumn of 1941, the Territories of Poland annexed by the Soviet Union, lands which were annexed by the Soviets were overrun by Germany in the course of the initially successful Operation Barbarossa, German attack on the USSR. After a few years of fighting, the Red Army drove the Wehrmacht, German forces out of the USSR and crossed into Poland from the rest of Central and Eastern Europe.

World War II
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), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chicago School (mathematical Analysis)
The Chicago school of mathematical analysis is a school of thought in mathematics that emphasizes the applications of Fourier analysis to the study of partial differential equations. Mathematician Antoni Zygmund co-founded the school with his doctoral student Alberto Calderón at the University of Chicago in the 1950s. Over the years, Zygmund mentored over 40 doctoral students at the University of Chicago. Key people * Antoni Zygmund * Alberto Calderón * Paul Cohen, Fields Medal winner (1966) Comments The Chicago school of analysis is considered to be one of the strongest schools of mathematical analysis in the 20th century, which was responsible for some of the most important developments in analysis. Awards In 1986, Antoni Zygmund received the National Medal of Science, in part for his "creation and leadership of the strongest school of analytical research in the contemporary mathematical world."

Harmonic Analysis
Harmonic analysis is a branch of mathematics concerned with the representation of functions or signals as the superposition of basic waves, and the study of and generalization of the notions of Fourier series and Fourier transforms (i.e. an extended form of Fourier analysis). In the past two centuries, it has become a vast subject with applications in areas as diverse as number theory, representation theory, signal processing, quantum mechanics, tidal analysis and neuroscience. The term "harmonics" originated as the Ancient Greek word ''harmonikos'', meaning "skilled in music". In physical eigenvalue problems, it began to mean waves whose frequencies are integer multiples of one another, as are the frequencies of the harmonics of music notes, but the term has been generalized beyond its original meaning. The classical Fourier transform on R''n'' is still an area of ongoing research, particularly concerning Fourier transformation on more general objects such as tempered di ...
