Algebraic number theory

Monogenic field

In mathematics, a monogenic field is an algebraic number field K for which there exists an element a such that the ring of integers OK is the subring Z[a] of K generated by a. Then OK is a quotient of the polynomial ring Z[X] and the powers of a constitute a power integral basis. In a monogenic field K, the field discriminant of K is equal to the discriminant of the minimal polynomial of α. (Wikipedia).

Monoclonal Antibodies | Health | Biology | FuseSchool

Antibodies are the warriors inside our body. They are part of our immune system, recognising and fighting against bad foreign invaders, called antigens. Antibodies can bind to a broad range of antigens, and are produced by cells of the immune system, known as B-cells. To learn more about

Non-monogenic Division Fields of Elliptic Curves, Hanson Smith

Abstract: This talk will serve as an exposition of a recent preprint investigating the division fields of elliptic curves. In this work we show that for various positive integers n there exist of infinite families of elliptic curves over Q with n-division fields, Q(E[n]), that are not mono

What is the definition of a monomial and polynomials with examples

👉 Learn how to classify polynomials based on the number of terms as well as the leading coefficient and the degree. When we are classifying polynomials by the number of terms we will focus on monomials, binomials, and trinomials, whereas classifying polynomials by the degree will focus on
