Radical of a ring

In ring theory, a branch of mathematics, a radical of a ring is an ideal of "not-good" elements of the ring. The first example of a radical was the nilradical introduced by , based on a suggestion of . In the next few years several other radicals were discovered, of which the most important example is the Jacobson radical. The general theory of radicals was defined independently by (Amitsur , , ) and . (Wikipedia).

Radicals of Ideals (and Geometry) - Feb 17, 2021 - Rings and Modules

We prove that the radical of an ideal is the intersection of primes containing it (I think). We also talk about the geometric meaning of the radical of an ideal.
