Erik Ivar Fredholm (fødd 7. april 1866 i Stockholm, død 17. august 1927) var ein svensk matematikar. Han var elev av Magnus Gustaf Mittag-Leffler og vart i 1898 dosent og i 1906 professor i mekanikk og matematisk fysikk ved Stockholms högskola .
Erik Ivar Fredholm (7. dubna 1866 Stockholm, Švédsko – 17. srpna 1927 Mörby, Švédsko) byl švédský matematik. Je známý především jako zakladatel moderní teorie integrálních rovnic . Článek, který v roce 1903 publikoval v časopise Acta Mathematica , je považován za jeden z milníků při vzniku teorie operátorů .
In mathematics, Fredholm operators are certain operators that arise in the Fredholm theory of integral equations.They are named in honour of Erik Ivar Fredholm.By definition, a Fredholm operator is a bounded linear operator T : X → Y between two Banach spaces with finite-dimensional kernel and finite-dimensional (algebraic) cokernel = / , and with closed range .
In the narrowest sense, Fredholm theory concerns itself with the solution of the Fredholm integral equation. In a broader sense, the abstract structure of Fredholm's theory is given in terms of the spectral theory of Fredholm operators and Fredholm kernels on Hilbert space. The theory is named in honour of Erik Ivar Fredholm.
Erik Ivar Fredholm (n. 7 aprilie 1866 la Stockholm - d. 17 august 1927 la Mörby lângă Stockholm) a fost un matematician suedez . A pus bazele teoriei moderne ale ecuațiilor integrale . Lucrarea sa, Acta mathematica, publicată în 1903, este considerată ca bază a teoriei operatorilor.
Erik Fredholm was a Swedish mathematician who founded the modern theory of integral equations. This became a major research topic in the first quarter of the twentieth century and underpinned important theoretical developments in physics; David Hilbert, in particular, extended Fredholm's work to arrive at the concept of Hilbert space.
