Polynomial ring — In mathematics, especially in the field of abstract algebra, a polynomial ring is a ring formed from the set of polynomials in one or more variables with coefficients in another ring. Polynomial rings have influenced much of mathematics, from the … Wikipedia
Radical of an ideal — In ring theory, a branch of mathematics, the radical of an ideal is a kind of completion of the ideal. There are several special radicals associated with the entire ring such as the nilradical and the Jacobson radical , which isolate certain bad… … Wikipedia
Harmonic polynomial — In mathematics, in abstract algebra, a multivariate polynomial over a field whose Laplacian is zero is termed a harmonic polynomial.The harmonic polynomials form a vector subspace of the vector space of polynomials over the field. In fact, they… … Wikipedia
Bring radical — In algebra, a Bring radical or ultraradical is a root of the polynomial :x^5+x+a, ,where a is a complex number. (The root is chosen so the radical of a real is real, and the radical is a differentiable function of a in the complex plane, with a… … Wikipedia

Irreducible polynomial — In mathematics, the adjective irreducible means that an object cannot be expressed as a product of at least two non trivial factors in a given set. See also factorization. For any field F , the ring of polynomials with coefficients in F is… … Wikipedia
Separable polynomial — In mathematics, two slightly different notions of separable polynomial are used, by different authors. According to the most common one, a polynomial P(X) over a given field K is separable if all its roots are distinct in an algebraic closure of… … Wikipedia
Cyclotomic polynomial — In algebra, the nth cyclotomic polynomial, for any positive integer n, is the monic polynomial: where the product is over all nth primitive roots of unity ω in a field, i.e. all the complex numbers ω of order n. Contents 1 Properties … Wikipedia
