26. Mai 2024 · Antoni Zygmund was a Polish-born mathematician who exerted a major influence on 20th-century mathematics, particularly in harmonic analysis, a field utilized in science and technology for the formulation of descriptions of periodic phenomena such as waves, vibrations, and regularly repeating.
Vor 3 Tagen · The Hilbert transform was a motivating example for Antoni Zygmund and Alberto Calderón during their study of singular integrals. Their investigations have played a fundamental role in modern harmonic analysis. Various generalizations of the Hilbert transform, such as the bilinear and trilinear Hilbert transforms are still active ...
22. Mai 2024 · During that time, Antoni Zygmund (1900–1992), one of the great Polish mathematicians from the generation of Stefan Banach (1892–1945), was still on the faculty there. I had the privilege of seeing and talking with Professor Zygmund. His example gave me living proof of the towering achievements of Polish science.
31. Mai 2024 · In 1982, he earned a Ph. D. in mathematics and science history from the University of Regensberg. His doctoral dissertation, which has been published in book form, was dedicated to the life & work of Antoni Zygmund, a distinguished mathematician of the twentieth century. In addition to his educational & research activities, Kit has ...
29. Mai 2024 · Concerned with elliptic operators with stationary random coefficients governed by linear or nonlinear mixing conditions and bounded (or unbounded) C1 domains, this paper mainly studies (weighted) annealed Calderón-Zygmund estimates, some of which are new even in a periodic setting.
Vor einem Tag · Sigismund III Vasa ( Polish: Zygmunt III Waza, Lithuanian: Žygimantas Vaza; 20 June 1566 – 30 April 1632 N.S.) was King of Poland and Grand Duke of Lithuania from 1587 to 1632 and, as Sigismund, King of Sweden and Grand Duke of Finland from 1592 to 1599. He was the first Polish sovereign from the House of Vasa.
24. Mai 2024 · Next, we show that the quantity that defines the weighted Lebesgue-Zygmund space satisfies the quasi triangular inequality and the scalar multiplication is continuous. Observe that we do not require absolute homogeneity for a set to be a quasinormed vector space.
