Generic matrices, ๐พโ, and unirational fields
This note is to announce new examples of unirational fields, which are not rational, in all characteristics.Here a field K is called rational over k if it is a pure transcendental extension of k (with finitely many variables).It is called unirational if it is contained in a rational extension.The interesting โฆ
