One field over another separated by a slash, with no quotient implied.
Also known as: Field extension, L over K, Extension notation
L/K reads 'L over K' and means L is a field containing K — the slash here is not division and not a quotient, which is a genuine trap given that the identical glyph means a quotient group two chapters earlier. The degree of the extension is written in square brackets.
Denotes a field extension: the upper field contains the lower one as a subfield.

Uses a slash that is neither division nor a quotient, unlike the visually identical G/N of group theory; the collision is a known source of confusion.

Carries its degree as [L : K], the dimension of the larger field as a vector space over the smaller.
