Franz Freudenthal
Franz P. Freudenthal is a Bolivian physician who is known for several medical inventions, including a device that can cure heart ailments in children. Career Franz P. Freudenthal was born in La Paz, Bolivia to German immigrant parents.

Thor Freudenthal
Thor Freudenthal (; born 20 October 1972) is a German film director, screenwriter, animator and special effects artist best known for his work on ''Diary of a Wimpy Kid'' and '' Percy Jackson: Sea of Monsters''. Life and career Freudenthal was raised in Berlin, Germany. His parents were born in Israel. He credits his early interest in cinema to Steven Spielberg, saying "When my mother told me he's Jewish, and he goes to synagogue, it was like, 'My God, we're of the same tribe, and he's a huge hero of mine.' And then seeing the '' Schindler movie'' actually made me feel more secure in who I was myself." His family's connection to Spielberg became real when his Polish-Jewish grandparents, survivors of the Holocaust who had known Schindler personally, were asked to appear in the final scene of the movie. Freudenthal attended the Hochschule der Künste Berlin, and later moved to Southern California as an exchange student at CalArts. He started out as an animation director, and fo ...

Axel Olof Freudenthal
Axel Olof Freudenthal (12 December 1836 – 2 June 1911), was a Swedish-speaking Finnish philologist and politician. He was born in Siuntio, and studied at the University of Helsinki where the nationalistic movement struggle between the Fennomans and the Svecomans was raging. He was a strong proponent of the use of Swedish in Finland, and subsequently established the theory that the Swedish-speaking population constituted a separate nationality. This theory strongly opposed any form of Finnicization, which it regarded as turning away from Western civilization, and even as a form of Russification. In its more extreme aspects, his theory connected language, nationality and race in a way that claimed supremacy of Swedes over Finns in a way that parallelled other contemporary theories of Aryan supremacy. Freudenthal was appointed a docent in 1866 in Old Norse language and wrote his doctoral thesis on the dialect of Närpes in 1878. He was a Professor of Swedish language and lite ...

Freudenthal Suspension Theorem
In mathematics, and specifically in the field of homotopy theory, the Freudenthal suspension theorem is the fundamental result leading to the concept of stabilization of homotopy groups and ultimately to stable homotopy theory. It explains the behavior of simultaneously taking suspensions and increasing the index of the homotopy groups of the space in question. It was proved in 1937 by Hans Freudenthal. The theorem is a corollary of the homotopy excision theorem. Statement of the theorem Let ''X'' be an ''n''-connected pointed space (a pointed CW-complex or pointed simplicial set). The map :X \to \Omega(\Sigma X) induces a map :\pi_k(X) \to \pi_k(\Omega(\Sigma X)) on homotopy groups, where Ω denotes the loop functor and Σ denotes the reduced suspension functor. The suspension theorem then states that the induced map on homotopy groups is an isomorphism if ''k'' ≤ 2''n'' and an epimorphism if ''k'' = 2''n'' + 1. A basic result on loop spaces gives the relation :\pi_k( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freudenthal Spectral Theorem
In mathematics, the Freudenthal spectral theorem is a result in Riesz space theory proved by Hans Freudenthal in 1936. It roughly states that any element dominated by a positive element in a Riesz space with the principal projection property can in a sense be approximated uniformly by simple functions. Numerous well-known results may be derived from the Freudenthal spectral theorem. The well-known Radon–Nikodym theorem, the validity of the Poisson formula and the spectral theorem from the theory of normal operators can all be shown to follow as special cases of the Freudenthal spectral theorem. Statement Let ''e'' be any positive element in a Riesz space ''E''. A positive element of ''p'' in ''E'' is called a component of ''e'' if p\wedge(e-p)=0. If p_1,p_2,\ldots,p_n are pairwise disjoint components of ''e'', any real linear combination of p_1,p_2,\ldots,p_n is called an ''e''-simple function. The Freudenthal spectral theorem states: Let ''E'' be any Riesz space with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
