A Hilbertian variety V over K is one for which V(K) is not thin: this is a birational invariant of V. A Hilbertian field K is one for which there exists a Hilbertian variety of positive dimension over K: the term was introduced by Lang in 1962. If K is Hilbertian then the projective line over K is Hilbertian, so this may be taken … See more In mathematics, a thin set in the sense of Serre, named after Jean-Pierre Serre, is a certain kind of subset constructed in algebraic geometry over a given field K, by allowed operations that are in a definite sense 'unlikely'.

THE EMBEDDING PROBLEM OVER A HILBERTIAN PAC-FIELD

WebApr 1, 2024 · Introduction. The inverse Galois problem over a field k, a question going back to Hilbert and Noether, asks whether every finite group occurs as a Galois group over k, i.e., as the Galois group of a Galois field extension of k.A stronger version asks for solutions to finite embedding problems over k.As in, e.g., [18, §16.4], say that a finite embedding … WebMar 27, 2010 · Any non-degenerate quadratic form over a Hilbertian field (e.g., a number field) is isomorphic to a scaled trace form. In this work we extend this result to more general fields, in particular, prosolvable and prime-to-p extensions of a Hilbertian field.The proofs are based on the theory of PAC extensions. ipd air filterWebDec 23, 2016 · Let G be a finite group and let K be a hilbertian field. Many finite groups have been shown to satisfy the arithmetic lifting property over K, that is, every G-Galois extension of K arises as a specialization of a geometric branched covering of the projective line defined over K.The paper explores the situation when a semidirect product of two groups … open university planning a project

WebWe show that any quadratic extension of Hilbertian fields of characteristic different from 2 can be embedded in an S n -extension (i.e. a Galois extension with the symmetric group S n as Galois group). For n ≠6, it will follow that A n has the so-called GAR-property over any field of characteristic different from 2.
