WebIn particular, the Paley-Wiener space P Wπσ corresponds to de Branges space H(Eσ ) where Eσ (z) = exp(−iπσz). The following characterization of a de Branges space can be found in [4, p. 57]: Theorem 3 A Hilbert space H of entire functions is equal isometrically to some de Brange space H(E) if and only if the following conditions hold: B1. In abstract algebra, Hilbert's Theorem 90 (or Satz 90) is an important result on cyclic extensions of fields (or to one of its generalizations) that leads to Kummer theory. In its most basic form, it states that if L/K is an extension of fields with cyclic Galois group G = Gal(L/K) generated by an element and if is an element of L of relative norm 1, that is then there exists in L such that

WebDavid Hilbert was a German mathematician and physicist, who was born on 23 January 1862 in Konigsberg, Prussia, now Kaliningrad, Russia. He is considered one of the founders of proof theory and mathematical logic. He made great contributions to physics and mathematics but his most significant works are in the field of geometry, after Euclid.
