Theorems in algebraic number theory
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 The theorem takes its name from the fact that it is the 90th theorem in David Hilbert's Zahlbericht (Hilbert , ), although it is originally due to Kummer . Often a more general theorem due to Emmy Noether is given the name, stating that if L/K is a finite Galois extension of fields with arbitrary Galois group G = Gal(L/K), then the first cohomology group of G, with coefficients in the multiplicative group of L, is trivial: (Wikipedia).
Galois theory: Hilbert's theorem 90
This lecture is part of an online graduate course on Galois theory. We discuss two forms of Hilbert's theorem 90: the original version for cyclic extensions, and Noether's more general version for arbitrary finite Galois extensions. The proofs use a lemma of Artin about the linear indepen

Dimitri Grigoryev - A Tropical Version of Hilbert Polynomial
We define Hilbert function of a semiring ideal of tropical polynomials in n variables. For n=1 we prove that it is the sum of a linear function and a periodic function (for sufficiently large values). The leading coefficient of the linear function equals the tropical entropy of the ideal.
