separable closure


Let K be a field and let L be an algebraic closureMathworldPlanetmath of K. The separable closure of K inside L is the compositum of all finite separable extensionsMathworldPlanetmath of K contained in L (that is to say, the smallest subfieldMathworldPlanetmath of L that contains every finite separable extension of K).
