Logical Difficulties with Cyclotomic Fields - Famous Math Problems 20

Explore the logical challenges surrounding cyclotomic fields in this mathematics lecture. Delve into the historical context of cyclotomic polynomials, tracing back to 19th-century work by Gauss. Examine the issues that arise when embedding cyclotomic fields into complex number fields, and how this approach can distort the purely algebraic nature of the subject. Investigate the classical "9th roots of unity" to illustrate the distinction between constructible zeroes and others in relation to ruler and compass constructions. Consider how infinite processes required in these concepts extend beyond the realm of algebra, highlighting the tensions between geometric interpretations and algebraic foundations in this area of mathematics.
