Abstract: The main goal of this work is to answer a question of Dèbes and Haran by relaxing the condition for Hilbertianity. Namely we prove that for a field K to be Hilbertian it suffices that K has the irreducible specialization property merely for absolutely irreducible polynomials.

In mathematics, Hilbert spaces (named after David Hilbert) allow generalizing the methods of linear algebra and calculus from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional. Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces. Formally, a Hilbert space is a vector space equipped with an inner product that defines a distance function for which the space is a complete metric space. WebSep 1, 2016 · Let K be a Hilbertian field, let G be a non-abelian finite group, and let Y be a rational variety over K. For any geometrically irreducible G-Galois cover E of Y K s that descends to a cover of Y there exists a finite extension L / K and an L-descent X ′ → Y L of that cover such that it does not descend to a cover of Y. Proof

WebNov 23, 2011 · The conjecture of Dèbes and Deschamps implies that over a Hilbertian field any finite split embedding problem is solvable. It is well known that a Henselian valued field (in particular, any field complete with respect to a valuation of finite rank) cannot be Hilbertian, thus it is natural to ask whether our fields are Hilbertian. WebThe first six chapters of the book give an introduction to the arithmetic of fields that is fairly standard, covering infinite Galois theory, profinite groups, extensions of valued fields, algebraic function fields (including the Riemann-Roch theorem, zeta functions and the Riemann hypothesis, proved using Bombieri’s approach), Dirichlet density …
