Perfect fields are significant because Galois theory over these fields becomes simpler, since the general Galois assumption of field extensions being separable is automatically satisfied over these fields (see third condition above). See more In algebra, a field k is perfect if any one of the following equivalent conditions holds: • Every irreducible polynomial over k has distinct roots. • Every irreducible polynomial over k is separable. See more Any finitely generated field extension K over a perfect field k is separably generated, i.e. admits a separating transcendence base, … See more • p-ring • Perfect ring • Quasi-finite field See more Examples of perfect fields are: • every field of characteristic zero, so $${\displaystyle \mathbb {Q} }$$ and every finite extension, and $${\displaystyle \mathbb {C} }$$; • every finite field $${\displaystyle \mathbb {F} _{q}}$$; See more One of the equivalent conditions says that, in characteristic p, a field adjoined with all p -th roots (r ≥ 1) is perfect; it is called the perfect closure of k and usually denoted by $${\displaystyle k^{p^{-\infty }}}$$. The perfect closure can be used in a test for separability. … See more • "Perfect field", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more Web1 day ago · REI. To buy: rei.com, $99.
