WebFeb 9, 2024 · Theorem (Hilbert’s irreducibility theorem). A number field K K is Hilbertian. In particular, for every n n, the affine space An(K) A n ( K) has the Hilbert property over K K. However, the field of real numbers R ℝ and the field of p p … 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 … See more More precisely, let V be an algebraic variety over K (assumptions here are: V is an irreducible set, a quasi-projective variety, and K has characteristic zero).

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. WebChapter 12.
