Frases de Carl Ludwig Siegel

Carl Ludwig Siegel foi um matemático alemão, especializado em teoria dos números.

Entrou para a Universidade Humboldt em 1915 como estudante em matemática, astronomia e física. Entre seus professores encontravam-se Max Planck e Ferdinand Georg Frobenius, cuja influência o fizeram abandonar a astronomia e dedicar-se à teoria dos números.



Seus trabalhos com teoria dos números, equações diofantinas e mecânica celeste em particular trouxeram-lhe diversas honras. Em 1978 recebeu o Prêmio Wolf de Matemática.

Carl Ludwig Siegel: Frases em inglês

“I am afraid that mathematics will perish by the end of this century if the present trend for senseless abstractin — as I call it: theory of the empty set — cannot be blocked up.”

in a 1964 letter to L. J. Mordell as quoted by [C. S. Yogananda, The Life and Times of Bourbaki, June 2015, Resonance, 556–559, http://www.ias.ac.in/article/fulltext/reso/020/06/0556-0559] (quote from p. 558)

“Ours, according to Leibnitz, is the best of all possible worlds, and the laws of nature can therefore be described in terms of extremal principles. Thus, arising from corresponding variational problems, the differential equations of mechanics have invariance properties relative to certain groups of coordinate transformations.”

“One of the many importants ideas introduced by Minkowski into the study of convex bodies was that of gauge function. Roughly, the gauge function is the equation of a convex body. Minkowski showed that the gauge function could be defined in a purely geometric way and that it must have certain properties analogous to those possessed by the distance of a point from the origin. He also showed that conversely given any function possessing these properties, there exists a convex body with the given function as its gauge function.”
