(algebra, field theory) A field K such that every irreducible polynomial over K has distinct roots.

(algebra, Galois theory) (of a polynomial) Given a polynomial p over a field K, the smallest extension field L of K such that p, as a polynomial over L, decomposes into linear factors (polynomials of degree 1); (of a set of polynomials) given a set P of polynomials over K, the smallest extension field of K over which every polynomial in P decomposes into linear factors.

ice formed in the polar seas in large surfaces, distinguished from icebergs

plural of algebra over a field

(algebra) A vector space (over some field) with an additional binary operation, a vector-valued product between vectors, which is bilinear over vector addition and scalar multiplication. (N.B.: such bilinearity implies distributivity of the vector multiplication with respect to the vector addition, which means that such a vector space is also a ring.)

An area of land or seabed where natural gas can be extracted in commercially viable quantities.
