... x over the field F . F is the field of coefficients of F [x]. Polynomial rings over fields have many of the properties enjoyed by fields. F [x] is closed and distributive nearly by definition. Commutativity and additive associativity for F [x] are easy consequences of the same properties for F , and ...

... On the other hand, let K be a locally compact field of characteristic p. Then its absolute ramification index is e = v(p) = v(0) = ∞. This may seem like a strange definition, but it’s a suggestive one, since for any n, K admits a subfield F such that e(K/F ) = n. In particular, there is no canonical ...

... Solution. We use the Euclidean Algorithm: first divide a(x) by b(x), then divide b(x) by the remainder, then divide the first remainder by the new remainder, and so on. The last non-zero remainder is the greatest common divisor. We have 2x3 + x2 − 2x − 1 = 2(x3 − x2 + 2x − 2) + (3x2 − 6x + 3) x3 − x ...

Root of unity



In mathematics, a root of unity, occasionally called a de Moivre number, is any complex number that gives 1 when raised to some positive integer power n. Roots of unity are used in many branches of mathematics, and are especially important in number theory, the theory of group characters, and the discrete Fourier transform.In field theory and ring theory the notion of root of unity also applies to any ring with a multiplicative identity element. Any algebraically closed field has exactly n nth roots of unity, if n is not divisible by the characteristic of the field.
