Algebraic closure
... completely into linear polynomials, that is, if and only if K has no proper algebraic extensions. Definition. A field extension F of F is called an algebraic closure if F is an algebraic extension of F and F is algebraically closed. Theorem. Every field F has an algebraic closure F . PROOF. The idea ...

Mining Multi-label Data by Grigorios Tsoumakas, Ioannis Katakis
... • Applications in ranking web pages. Web pages are often multi labeled. For example “cooking” and “food network” and “iron chef” might all apply to the same page. How do you rank and classify that along other pages that have some of the same labels, but not all of the same labels? ...

... are in F. So our usual set of polynomials is R[x]. We then denote by F(x) the set of all fractions of elements of F[x] (just don’t divide by zero). Our field of rational functions from earlier, which is just the set of fractions whose numerator and denominator are members of R[x], is R(x). Now here ...

... degree of ε is 2 ε satisfies a quadratic equation, a0 ∗ x2 + a1 ∗ x + a2 = 0. so, ε = a + b ∗ m/c for some√ integers a, b, c, m where m doesn’t have a squared factor. It is easily verified that K(ε) is the same as K( m) for some square-free rational integer m, positive or negative, apart from 1. Her ...
